Question

Select the answer for x to the second power = 75 (out of the answers provided) and x to the third power = 16. I'm really struggling!

Answer 1

Answer is a for both questions
$x^2=75$
Inverse of squared is square root.  $x= \sqrt{75}$
$x= \sqrt{25*3}$
$x=5 \sqrt{3}$

$x^3=16$
$x= \sqrt[3]{2*2*2*2}$  prime factorization of 16
$x=2 \sqrt[3]{2}$   a set of 3 comes out as one number...i.e. 2
