Simplify the expression.<br>Write your answer without negative exponents. NEED AN ANSWER ASAP​
harina [27]

Answer:

\boxed{\frac{-3b^4 }{a^6 }}

Step-by-step explanation:

\frac{-18a^{-8}b^{-3}}{6a^{-2}b^{-7}}

\frac{-18}{6} \times \frac{a^{-8}}{a^{-2}}  \times \frac{b^{-3}}{b^{-7}}

-3 \times \frac{a^{-8}}{a^{-2}}  \times \frac{b^{-3}}{b^{-7}}

Apply the law of exponents, when dividing exponents with same base, we subtract the exponents.

-3 \times a^{-8-(-2)}  \times b^{-3- (-7)}

-3 \times a^{-8+2}  \times b^{-3+7}

-3 \times a^{-6}  \times b^{4}

{-3a^{-6}b^{4}}

The answer should be without negative exponents.

a^{-6}=\frac{1}{a^6 }

\frac{-3b^4 }{a^6 }
