Question

If x to the second power equals 20 what is the value of x?

Answer 1

Hey there!

Let's set up an algebraic equation to represent this problem:

$x^2=20$

In order to get rid of the squared, we need to take the square root of both sides, therefore, our answer is:

$x= \sqrt{20}$

Your answer is the square root of 20.

Hope this helps!

Answer 2

square root 20 = 4.472135955
So x=4.472135855
