Question

Simplify the expression without negative exponents ​

Answer 1

Answer: $-50a^{11}b^{9}$

Step-by-step explanation:

Any negative exponent can be moved to the other side of the fraction as a positive exponent.$\frac{1}{x^{-3}}=x^3\\ \frac{x^{-3}}{1}=\frac{1}{x^3}$

Thus, simply move the negative exponents from the bottom into the numerator to get. -10a^2*b^4*5a^9*b^5.  Then, use the exponent rule to get $-50a^{11}b^{9}$
