You are most welcome. Sorry about the typo before, I am new to notation on the computer. I don't have much time, so please be as fast as possible, in half an hour I have to leave (it is due tomorrow morning!!! ).

I have tried my best, and correct me if I am wrong:

1. p^6q^4 divided by p^q
= (pq) ^3

2. 8w^10 divided by 2w^4
= w^12

3. 2x^6 multiplied by 5x, divided by 10x^4
= 13x / 14x

4. (2g^2)^2
= 2g^4 OR g^6 ???

5. 20d^8e^6 divided by 2d^2e multiplied by 5d^2e^2
= d^17 X e^4


I have written down the rules as well to help me in future.
