Help on this ALGEBRA QUESTIONS !!!

Simplify the expression, if possible. 512 ^1/2

A. 32
B. 16√ 2
C. 64
D. It's not a real number.

Answer 1

Note that
`x^{(1)/(2)}=\sqrt[2]{x}`

Which means that:

`512^{(1)/(2)}=\sqrt[2]{512}=\sqrt[2]{16^2\cdot2}=\boxed{16\sqrt[2]{2}}`

the answer is B.

Hope this helps.
