$3 \cdot a \cdot b \cdot \sqrt{b}$ $3*a*b*sqrt(b)$

Explanation:

$\frac{\sqrt{9 \cdot 10 \cdot a^{3} \cdot a^{2} \cdot b^{3} \cdot b^{4}}}{\sqrt{10 \cdot a^{3} \cdot b^{4}}}$ $(sqrt(9*10*a^3*a^2*b^3*b^4))/(sqrt(10*a^3*b^4))$
= $3 \cdot a \frac{\sqrt{10 \cdot a^{3} \cdot b^{4}} \cdot (\sqrt{b^{2} \cdot b})}{\sqrt{10 \cdot a^{3} \cdot b^{4}}}$ $3*a(sqrt(10*a^3*b^4)*(sqrt(b^2 *b)))/(sqrt(10*a^3*b^4))$
= $3 \cdot a \cdot b \cdot \sqrt{b}$ $3*a*b*sqrt(b)$
