Sagot :

Answer: D) cube root of 16

================================================

Explanation:

The rule we use is

[tex]x^{m/n} = \sqrt[n]{x^m}[/tex]

In this case, x = 4, m = 2 and n = 3.

So,

[tex]x^{m/n} = \sqrt[n]{x^m}\\\\\\4^{2/3} = \sqrt[3]{4^2}\\\\\\4^{2/3} = \sqrt[3]{16}\\\\\\[/tex]

Showing that the original expression turns into the cube root of 16.
