Question

What is the cube root of 216x9 y18 ? A. 4x3 y6 B. 6x3 y6 C. 72x6 y15 D. 213x6 y15

Answer 1

Option B.

6*(x^3)*(y^6)

Explanation:

Please see attached picture for the answer to the problem

We know that

6^3 = 216

So,

∛216 = 6

∛x^9 = x^3

∛y^18 = y^6

And,

∛216*∛x^9*∛y^18 = ∛(216*x^9*y^18)
