What the answer to this all of those
zvonat [6]
So much stuff at once...
I'm only going to give you the information needed to do this.

All of these involve the 4 main exponent laws.

1) Multiplying.
    When you multiply two 'numbers' that share the same base, you add               exponents and keep the base the same. (ex. 4g²(4g⁴) = 4g²⁺⁴ = 4g⁶)

2) Dividing.
    When you divide two 'numbers' that share the same base, you subtract      exponents and keep the base the same. (ex. 3a⁷ / 3a⁴ = 3a⁷⁻³ = 3a³)

3) To the power of 1.
    Anything to the power of 1 is the same. (ex. 5a¹ = 5a)

4) To the power of 0.
    Anything to the power of 0 = 1. (ex. 2d⁰ = 2(1) = 2)

This should help.
