Question

Which is equivalent to 216^1/3 A. 3 B. 6 C. 36 D. 72

Answer 1

6

Explanation:

The question is asking what is the cubic root of 216? Conventionally, this is written two ways:

`216^(1/3)` or
`\sqrt[3]{216}`

You should be familiar with square roots.
`√(25)=5` because 5 x 5 = 25

For cubic roots, you are asking __ x __ x __ = 216 ?

Since 6 x 6 x 6 = 216,
`216^(1/3)=6`
