Question

Please give explanation w answer, thanks :)

Answer 1

216 raised to the power 1/3 can also be written as cube root of 216. 

Changing the given expression to radical form, we can write:

$(216)^{ \frac{1}{3} } \\ \\ = \sqrt[3]{216}$

216 is the cube of 6 i.e. multiply 6 three times (6 x 6 x 6), you will get 216.
So we can write the above expression as:

$\sqrt[3]{(6)^{3} }$

The cube root and cube cancel out each other, leaving the answer equal to 6.

So, the correct answer is option B
