Question

I need someone to walk me through this problem. The subject is "multiplying and dividing monomials to a power." This is the problem: 2r^-2*r^-1
It would be very helpful if someone can teach me to "flip" the answer, as my teacher says it. Please and thank you.

Answer 1

\[2r ^{-2}*r ^{-1}\]
I don't know if it helps to see the problem like this, but here....
