1. The problem statement, all variables and given/known data (3p^-3 q^-1)^2 x (-4p^3 q^-2)^2 = ? Leave answer in positive indices 2. Relevant equations 3. The attempt at a solution (3p^-3 q^-1)^2 x (-4p^3 q^-2)^2 = (9p^-6 q^-2)(16p^6 q^-4) = 144q^-6 = 144/q^6 Is my answer correct or I am missing a concept? Thank you for taking the time to read.
