Question

Simplify fully a) 8c²d^5 ÷ 2c³d³ b) 9a³b^5 ÷ 3ab²

Answer 1

Answer:

Step-by-step explanation:

In exponent division, if base are same , subtract the exponents.

$\frac{a^{m}}{a^{n}}=a^{m-n} , m>n\\\\ \frac{a^{m}}{a^{n}}= \frac{1}{a^{n-m}}, m$

a) 8c²d⁵ ÷ 2c³d³ = $\frac{8}{2}* \frac{d^{5-3}}{c^{3-2}}= 4*\frac{d^{2}}{c}= \frac{4d^{2}}{c}$

b) 9a³b⁵ ÷ 3ab² = $\frac{9}{3}* a^{3-1}*b^{5-2} = 3a^{2}b^{3}$

Answer 2
