Question

Can someone help me with this ??

Answer 1

Answer:

$\frac{\bf{cd^7}}{\bf{c^6d \cdot c^4d^9}}=\frac{\bf{1}}{\bf{c^9d^3}}$

Step-by-step explanation:

Given expression is $\frac{cd^7}{c^6d \cdot c^4d^9}$

$\frac{cd^7}{c^6 d \cdot c^4d^9}=\frac{c d^7}{c^{10}d^{10}}$ by using the formula $a^m+a^n=a^{(m+n)}$

$\frac{c d^7}{c^6 d\cdot c^4d^9}=\frac{c}{c^{10}}\cdot\frac{d^7}{d^{10}}$

$\frac{c d^7}{c^6 d\cdot c^4d^9}=\frac{c^-9}{d^-3}$ by using the formula  $\frac{a^m}{a^n}=a^{(m-n)}$

$\frac{c d^7}{c^6 d\cdot c^4d^9}=\frac{1}{c^9d^3}$ by using the formula  $\frac{1}{a^m}=a^{-m}$
