Square roots are the inverse of squaring (Similar to how division is the inverse of multiplication)
And as such the square root of any number is equal to what number squared equals that number
For Example
Because
\({2}^{2}=4\)
2 squared equals four
Then
\(\sqrt{4}=2\)
the square root of four equals two
| \(\sqrt{4}=-2, 2\) | \({2}^{2}=4,{-2}^{2} = 4\) |
| \(\sqrt{9}=-3,3\) | \(9 = {3}^{2}, 9={-3}^{2}\) |
| \(\sqrt{16} = 4\) | \(4 *4=16, -4 *-4=16\) |
| \(\sqrt{25} = 5\) | \(25 = 5*5, 25 = -5*-5\) |
| \(\sqrt{{x}^{2}}= -x, x\) | \(x * x = {x}^{2}, -x*-x = {-x}^{2}={x}^{2}\) |
