More importantly how do you figure out the answer if it is a question with this many powers?

do just like you would with numbers, break them down into prime factors. Then "collect" them so all are represented.

3x^2 = 3*x*x

12y = 3*2*2*y

10x^3y^3 = 2*5*x*x*x*y*y*y

so we need: 2*2*3*5*x*x*x*y*y*y

= 60x^3y^3
