Question

Please explain i totally forgot how to do these it’s been forever.There are two of them there all 3 except for the 2 and 7 i have had handwriting.

Answer 1

$\sqrt[3]{2^3}=2$

The answer is 2 because the 3's at the exponent and at the root simplify themselves. Same as in d.

$\sqrt[3]{7^3}=7$

Looking at the drawing, we can just simplifying the exponent and the root when they are equal.
