Question

what is (-3y^-3)^-3 does the third power get drisbuted to the rest of the problem or just to the y^-3 and why

Answer 1

The -3 Power (that is outside the parenthesis) does get distributed. The parenthesis is containing the whole expression and the -3 is being multiplied to it as a whole. If the parenthesis weren't there, it would be part of the -3y^-3.
