HINT: \[c^{-n} = \frac{ 1 }{ c^n }\]

OpenStudy (mertsj):

\[\frac{c ^{-7}x^6}{x ^{-2}c ^{-2}}=\frac{c^2x^2x^6}{c^7}\]

OpenStudy (mertsj):

Cancel the common factors.

OpenStudy (abb0t):

Also, \[\frac{ a^n }{ a^{-n} } = \frac{ a^n }{ a^{-(-n)} }\]

OpenStudy (abb0t):

\[\frac{ a^n }{ a^{-(-n)} } = a^{n-(-n)} = a^{n+n}\]

OpenStudy (anonymous):

Ok I got D as the answer! Is it correct? @abb0t @Mertsj

OpenStudy (mertsj):

Good job!!

OpenStudy (abb0t):

Yes, good job!
