but square root 8 is 2 rad 2
is it \(8x^{\frac{1}{2}}\) or \((8x)^{\frac{1}{2}}\) ?
|dw:1363058722762:dw|

\[\sqrt{8x^2}=\sqrt{8}\times\sqrt{x^2}=\sqrt{2^2\times2}\times x=2x\sqrt{2}\]
yea that is a good point @satellite73 because if it is 8x^1/2 then you would find the square root of x and multiply 8. If it was (8x)^1/2 then you would find the square root of the whole thing (8x)
