$3^{3} \sqrt{a^{4} b^{2}} + 7 a \sqrt[3]{a b^{2}}$

Step 1

Raise $3$ to the power of $3$ .

$27 \sqrt{a^{4} b^{2}} + 7 a \sqrt[3]{a b^{2}}$

Step 2

Rewrite $a^{4} b^{2}$ as ${(a^{2} b)}^{2}$ .

$27 \sqrt{{(a^{2} b)}^{2}} + 7 a \sqrt[3]{a b^{2}}$

Step 3

Pull terms out from under the radical, assuming positive real numbers.

$27 a^{2} b + 7 a \sqrt[3]{a b^{2}}$
