Answer
$ac\sqrt [5] {-40a^2b^3}$
Work Step by Step
Rewrite the radicand as the product of factors such that you can take the fifth root of certain factors:
$\sqrt [5] {-40 • a^5 • a^2 • b^3 • c^5}$
Take the fifth roots of terms to take them out from under the radical sign:
$a • c\sqrt [5] {-40a^2b^3}$
Multiply the coefficients to simplify:
$ac\sqrt [5] {-40a^2b^3}$
