Answer
$\color{blue}{3tu^2\sqrt[5]{s^3}}$
Work Step by Step
Factor the radicand so that at least one factor is a perfect fifth power:
$=\sqrt[5]{243t^5u^{10}(s^3)}
\\=\sqrt[5]{3^5t^5(u^2)^5(s^3)}$
Bring out the fifth root of the perfect fifth power factors to obtain:
$=\color{blue}{3tu^2\sqrt[5]{s^3}}$
