What is the quotient of -8x∧6 over 4x∧-3 ??

Allushta [10]

Answer:

$-2x^{9}$ is the quotient

Step-by-step explanation:

We have two expression $-8x^6$ and $4x^{-3}$

We need to find quotient of this expression using exponent law.

First we write as quotient form,

$\Rightarrow -\dfrac{8x^6}{4x^{-3}}$

$\Rightarrow -2x^{6-(-3)}$ $(x^m\div x^n=x^{m-n})$

$\Rightarrow -2x^{6+3}$

$\Rightarrow -2x^{9}$

Thus, $-2x^{9}$ is the quotient of $-8x^6$ and $4x^{-3}$ .
