Question

Can someone help me with this ??

Answer 1

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

Explanation:

Given expression is
`(cd^7)/(c^6d \cdot c^4d^9)`

`(cd^7)/(c^6 d \cdot c^4d^9)=(c d^7)/(c^(10)d^(10))` by using the formula
`a^m+a^n=a^((m+n))`

`(c d^7)/(c^6 d\cdot c^4d^9)=(c)/(c^(10))\cdot(d^7)/(d^(10))`

`(c d^7)/(c^6 d\cdot c^4d^9)=(c^-9)/(d^-3)` by using the formula
`(a^m)/(a^n)=a^((m-n))`

`(c d^7)/(c^6 d\cdot c^4d^9)=(1)/(c^9d^3)` by using the formula
`(1)/(a^m)=a^(-m)`
