Question

Find the product.

-7(-a^2)(-b^3)

Answer 1

Since none of them are like terms, just remove the parenthesis:

\[-7a^2b^3\]

Answer 2

Note that I made the variables positive since they were both negatives being multiplied.

Answer 3

I may be wrong though, but as far as I know they can't be multiplied unless we know the value of a and b.
