Answer
$30m^3n^5\sqrt {5n}$
Work Step by Step
Rewrite the radicand as the product of factors such that you can take the square root of certain factors:
$5mn^3\sqrt {6^2 • 5 • m^4 • n^4 • n}$
Take the square roots of terms to take them out from under the radical sign:
$5mn^3 • 6m^2 • n^2\sqrt {5n}$
Simplify the radical by multiplying the coefficients:
$30m^3n^5\sqrt {5n}$
