    \[\Large a^{-b} \to \frac{1}{a^b}\]Do you know about this property?

    So what i did was there was a negative exponent '-b'. So I flipped the fraction, making the -b to +b. Do you get it?

    but how would you do it for this problem?

    Let's take c^-5 first. It have a negative exponent. so:\[\Large c^{-5} \to \frac{1}{c^5}\] We flipped the fraction. Making the exponent postive. Got it?

    yeah so then we would have 1/c to the 5 power?

    Essentially it looks like this: \[(\frac{ 1 }{ 3^2 })\times (\frac{ 1 }{ c ^{5} })\times (d ^{5})\] So therefore, in the end it will look like this: \[\frac{ d ^{4} }{ 9c ^{5} }\]

    oops, in that first equation I wrote \[d ^{5}\]I meant \[d ^{4}\]
