$3a^{2}b\sqrt {10a}$

Work Step by Step

$\sqrt {90a^{5}b^{2}}$ =$\sqrt {90}\times\sqrt {a^{5}}\times\sqrt {b^{2}}$ =$\sqrt {9\times10}\times\sqrt {a^{4+1}}\times\sqrt {b^{2}}$ =$3\sqrt {10}\times a^{2}\sqrt {a}\times b$ =$3\times a^{2}\times b\times\sqrt {10}\times\sqrt {a}$ =$3a^{2}b\times\sqrt {10\times a}$ =$3a^{2}b\sqrt {10a}$
