I condemn your teacher or your textbook for using the phrase "without rational notation," which has no meaning. ANY notation that isn't "irrational" is arguably rational. I hate teachers and textbooks who make up their own language and then insist that you learn it, without regard to the conventions of the discipline as a whole.

That said, the instruction "move all the terms to the numerator" DOES make sense, and the answer would then be

a^6 b^(-7)
