Question

Multiply and simplify

Answer 1

start by multiplying inside the radical to get
\[\sqrt[3]{12m^8}\]

Answer 2

then there is nothing you can do with the \(12\) inside, because 12 contains no perfect cubes, but
\[\sqrt[3]{m^8}=m^2\sqrt{m^2}\] because 3 goes in to 8 twice, with a remainder of 2
final answer is therefore
\[m^2\sqrt[3]{12m^2}\]
