Question

How do you simplify `(2b ) ^ { \frac { 3} { 5} }`?

Answer 1

`root(5)(8b^3)`

Explanation:

There really isn't much we can do here, besides writing it as a radical.

Know that, `root(b)(a^n)=a^(n/b)`.

`:.(2b)^(3/5)=root(5)((2b)^3)`

Simplifying `(2b)^3` into `8b^3`, we get

`root(5)(8b^3)`

That would be the final answer.
