Now we know that square root of 2 is an Irrational number. If you use a calculator to calculate the value of Root 2 you will get something like 1.4142135 and so on. This value that you get is actually non-terminating. It is never ending. Also, you will not find any pattern in the digits after the decimal. Hence, it’s also called a non-recurring decimal. There is no pattern that occurs again and again. These kinds of numbers are called Irrational numbers. Consider square root of 3 for instance. You will get its value as 1.732050 and so on. Even this decimal is non-terminating and non-recurring. So root 3 is also an Irrational number. You can try calculating the values of root 5, root 6, root 7 or root 8, you will find that all of them result in non-terminating, non-recurring decimals. But wait… root 9 equals 3. This is a Rational number. Yes, root 9 is not an Irrational number. In fact, square root of any perfect square will be a Rational number. But the square root of any number which is not a perfect square will always result in an Irrational number. Here’s the interesting part. If you know these two points well, you can even form an Irrational number by yourself. Let’s see how. We have to form a number which does not end and does not repeat any pattern. Something like 2.01001000100001 and so on. Here, the number does not end and is also non-recurring. This means that there is no pattern that repeats forever. You can even have a number like 15.2349449444944449 and so on This is also Irrational as it is non-terminating and non-recurring. Where does this concept help us? Say your are asked to find two Irrational numbers between 1.23 and 1.25. Remember, 1.24 is incorrect as its terminating. We need a non-terminating, non-recurring decimal. Yes, but we know that 1.24 is between these two numbers. After 1.24 we can start writing 010010001 and so on. That’s one Irrational number between these two numbers. Again, let’s write 1.24 and this time we write 020020002 and so on after it. That’s your second Irrational number. So to find Irrational numbers between two numbers, just write a Rational number between them and then add non-terminating, non-recurring digits after it.

Can you define irrational number and rational number

Very good mam

You speak UK in video

Is 23,49,64,81 an irrational number?

Mam how to prove it … Irrational number

Plz tell me……how to prove it

Aren’t these just real numbers?

Zedo zedo zedo one….beat drops.

Which app you created this vedio

I was taking a test as I watched this

Nice

Nice bonice

2/0 is a rational no or not

Nice explanation…

Thank you for this vdo…

Thank you so much

Thanx

what about 19/17, it gives us a non repeating non terminating decimal, yet its not irrational

How many irrational numbers between 2 and 7

u are great … i have a test in school so I subscribed ur channel and understanding u … Thank you sooo much for that. ..

2.01001000100001000001000000100000001000000001000000000100000000001…

best of learn more test

Are there any irrational numbers that contain more of one digit than another, i.e. the distribution of the ten digits is not uniform?

Thanks now I understand this concept😊😊

I was absent the day this concept was taught in school and I had no idea what irrational numbers were. I saw your video and now I have a better understanding than my class fellows!

THANK YOU SOOOO MUCH. I REALLY APPRECIATE YOUR EFFORTS!! Really helped

Please tell us how to calculate square number to decimal

Best teacher ever

only needed like 30 seconds of the video lol thanks

It helped me Soo much tomorrow iz my exams hope this will help me Inshallah

Good explanation👌

Thank you….

What if the numbers after decimal is recurring but not terminating?is it rational or irrational? Pls rply

Grt explaination

If it is 2.84848484…..

Then it is also not terminating

But it is recurring decimal

Then what about this ???

Make a vedio based on calender sums

Hi. Im new to this channel and i already love it. More videos please.

This video is really helpful.

Thank you🤗👍👍

((((10 to the 100th power )))))U SOUND LIKE SIRI'S SISTER …wen u said 010010001 (it would be grt if u went so on)…LOL…..

Thank you soo much

ummmmm. I was trying to relearn how to do this and this ad comes up "sick of searching up math help from 6 years ago" like wtf google

Thanks mam today is my maths exam you help me ☺

I like our chanel

I love how all of you are like "I have a math test tomorrow thx for the help"…. And left it to the last minute to learn something that'll probably only give you two marks out of a how many marker exam 😂

Superlykkkk. Respect from india

Thanks! I get it now :p

I learned something new today!!!! Yay!!!

Great explanation

Thanks so so much I has test tomorrow but I don't know about this irrational number

Now I know all the things about real number rational number and irrational number

i wanted to watch this tutorial but the girl had an indian accent so i clicked away

I'm new to this channel..thank u so much for the video it's really helpful👍👍

I really appreciate you for making this in English

I am a non-indian speaking person who is in a Indian school that follows the CBSE system

Wait i'm hungry

49=Fortnite?

THANKU MAM ……. YOU TEACHES SO WELL…………….. THANK YOU MAM

Nice and clear explanations no doubtss

Is 7/6 an irrational number? ur explanation needs some more examples to get glarity. Anyway goodwork

Thanks so much ,Clear Explanation ,thanks again

Is the number 1.373822738339328474 irrational

It is terminated by the way

Nice vedio

Well explained

Vry helpful

Thanks for the video

Super explained u r ASM

Wonderful technique best lecture ever

Make a video on transcendental numbers…gud vid 😇😇

Thank you for removing my little dout

You guys are pretty amazing!

i love the way you teach

5+√5 is rational or irrational

You sound really telgu

How we get square root of 2 values 1.4142135 without using calculator.. Plzzz reply mam

I can't understand Indians no offenses i just cant. All i hear it. Da numba is to

Thank you so much for making this videos. It helped so much

Your video are fabulous but you speak Hindi and English both plz

How can you tell whether it actually has no pattern or mathematicians just haven't yet discovered the pattern?

Sir,can you tell me which application is you use for making these type of videos???

I have a small youtube educational channel,your answer will help me to improve my channel..

plz give the name of the software???

REALLY GOOD I'M REALLY LIKE

Really,helpful.

👍️👍️

in english please

Very good

you made a mistake when saying square root of imperfect square is irrational because 2.25^1/2 or root 2.25=1.5 which is rational

😘

I searched all over the internet to find a video I understand and I couldn’t find one, but I found this and I actually understand so thank you so much this was really helpful :))

can we write 1/√2

Nice video

Ur the best I'm subscribed love this channel

Sike ur gay😛😂😂😂

good

very nice

Thankyou so much

Those 216 dislikes are from the teachers 😉 because it will fire them

**you and your channel you dont know how to explain a simple thingIrrational Number: The amount of money your teenager wants.

Thanks..Useful one..🔥💞
