I just recently started relearning math as an adult, this should be easy but I have trouble understanding what the actual question is. I am not just looking for the answer to this, I merely wish to understand what the question is asking.
Express each of the following expressions in the form $2^m3^na^rb^s$, where $m$, $n$, $r$ and $s$ are positive integers.
a) $8a^2b^3(27a^4)(2^5ab)$
