Answer
$5\sqrt 3+3\sqrt 10$
Work Step by Step
We can use the distributive property to simplify the given expression.
$\sqrt 3(5+\sqrt 30)=(\sqrt 3\times5)+(\sqrt 3\times\sqrt 30)=5\sqrt 3+(\sqrt (3\times30)=5\sqrt 3+\sqrt 90=5\sqrt 3+\sqrt (9\times10)=5\sqrt 3+3\sqrt 10$
Recall that $\sqrt 9=3$, because $3^{2}=9$.
