Question

How root 2 = 1/2 upon 2

Answer 1

Step-by-step explanation:

Sqrt(2) * Sqrt(2)/Sqrt(2) yields

Sqrt(2)/( Sqrt(2) * Sqrt(2) ).

Now, multiplying roots by each other yields a square root of the multiplication product of the numbers under the root. So:

Sqrt(2) * Sqrt(2) = Sqrt(4) which equals 2.

So plugging it back in...

Sqrt(2)/( Sqrt(2) * Sqrt(2) ) = Sqrt(2) / (2)

Therefore, in total, Sqrt(1/2) = Sqrt(2) / 2.

It will probably help if you write this out in the proper notation

Answer 2

Answer:

$\sqrt{2} = {2}^{ \frac{1}{2} }$

When both are equals to 'x' they must be equal to each other also.
