Square Root of 2

Two is not a perfect square Which means there is not a whole number multiplied by itself that equals 2. For example, the square root of 4 is 2 because 2 x 2 = 4

The square root of 2 is an irrational number.
Here it is written out 65 places,
1.41421356237309504880168872420969807856967187537694807317667973799,
but most of the time you should be ok using 1.4142.
The square root two can be represented as a fraction as 99/70
The square root of 2 is equal to the length of the hypotenuse of an isosceles right triangle with legs of length 1.

0:36 – no, it cannot (maybe just partially) because it is irrational, which means it cannot be, by definition, expressed as a ratio (fraction)…

How do you come up with the 1.41 without using a calculator?

this just sounds your saying "it is what it is"with no reasoning

i am so confused
this explained nothing

So b × 1.4142 is always equal to the long length of A paper and this ratio allows for the paper to be infinitely folded widthwise and maintain the same ratio. I wonder why they would use this ratio especially since it's not seemingly related to the hypotenuse. I'm thinking that there is a Universal usage for this ratio beyond it being the hypotenuse. I guess it has to do with infinite scalability? This is very interesting to me because I've been researching the Pythagorean theorem for about a week as it relates to physics. I feel like the √2 is used in physics beyond it being the hypotenuse of a right triangle with legs equal to one. I have more feelings about physics than knowledge but that's ok cause I think feelings are the foundation of physics. 🤗

The square root of 2 is an Irrational number.

There is no whole number that equal 2.... so it has to be 1.414..


Ummmm 1 x 1 would equal 2 if they didn't make it equal 1.

1x1 equal 2 makes more sense than
1.414 x 1414 = 1.9999396. 😅

I guess it, d be 1.4142135623731 because calculator says 1.4142135623730^2= so 1.4142135623731^2=2

So, what is the square root of 2% squared. The answer that I've been given is 1.41%. I'm not following. If 2% squared is .0004 and the square root of .0004 is .02 how can the answer be 1.41% instead of 2%?
