Answer 7

The parentheses just mean multiplication. You can get rid of them and simplify.

Remember that a^n * a^m = a^(n+m).

Answer 8

Try regrouping them.
For example, the first one:
(2x^2y^3)(-5x^4y^2)
2 * x^2 * y^3 * -5 * x^4 * y^2
(2 * -5)(x^2 * x^4)(y^3 * y^2)
(-10)(x^(2+4))(y^(3+2))
-10x^6y^5

Answer 9

okay im going to try that

Answer 10

Answer 11

Yup.

Answer 12

a^n * a^m = a^(n+m)
(a^n)^m = a^(nm)

Those are all you need to know for this.
