Question

choose the correct simplification of the expression (xy^3)^5

Answer 1

$(xy^3)^5=x^5y^{15}$

Here, we want to simplify the given expression

We use the general indices rule below to evaluate this;

$(n^a)^b=n^{ab}$

So, basically we have to multiply the powers outside and the powers inside the bracket

Thus, we have this as;

$(xy^3)^5=x^5y^{15}$
