a. 4cd² b. 3a²b³

Step-by-step explanation:

$\frac{8c^4d^5}{2c^3d^3}$

= $\frac{8}{2} ( \frac{c^4}{c^3} )(\frac{d^5}{d^3})$

= $\frac{4}{1} (\frac{c}{1}) (\frac{d^2}{1} )$ Reduce number. Substract exponent largest power

smallest power

= 4cd²

b. $\frac{9a^3b^5}{3ab^2}$

$\frac{9}{3} (\frac{a^3}{a} ) (\frac{b^5}{b^2} )$

$\frac{3}{1} (\frac{a^2}{1}) (\frac{b^3}{1} )$ Reduce number. Substract exponent largest power

smallest power

= 3a²b³
