Answer: To eliminate negative exponents, you move the whole factor to the denominator, if possible. Repeated exponentiation multiplies exponents.
Step-by-step explanation:
[tex](x^{-7})^6 = \left({\frac{1}{x^7}}\right)^6 = \frac{1}{x^7} \frac{1}{x^7} \frac{1}{x^7}\frac{1}{x^7} \frac{1}{x^7} \frac{1}{x^7}=\frac{1}{x^{42}}[/tex]
