I'm really stuck on these problems-
Simplify 6xy(3xy)^-2? I think this is 2/3xy
choices were
2/xy
3xy
2xy
2/3xy


Simplify 12xyz^-2/8x^-2z
choices were 3x^2y/2z^3
3x^3y/z^3
3x^3y/2z^3
x^3/2z^3

I think it is 3x^3y/2z^3

Thank you for checking

Thank you

1. Correct, assuming it is 2/(3xy)
2. Correct, assuming it is 3x³y/(2z³)
