Simplify the expression.<br><br>Write your answer without negative exponents.​
pantera1 [17]

Answer: \frac{5a^2}{-10a^4b^9}

Step-by-step explanation:

Any negative exponent can be moved to the other side of the fraction as a positive exponent.

Thus, simply move the negative exponents to get: 5a^2/b*b^8*-10a^4.  Then, use the exponent rule to get 5a^2/-10a^4b^9

Hope it helps <3
