Hi, I am new to the forum. I have been stuck on a few math problems involving exponents for a while now and i don't know where else to turn.

I have attached a pdf file with my work and the questions i need help with are as follows. * These are not going to be marked and we were given most of the answers, so please explain to me and don't just give me the answer

as you can see all the answers are already given so i'm not trying to cheat.. or be lazy and get people to work for me.. I benefit in no way whatsoever.

section a

2.a) Okay the answer for this one is supposed to be 3 √1/32

2.b) same as 2.a idk..

The rest i get

Then tosection B

9.) i)

ii)

Please explain these. There are more i don't understand but i'm hoping by you explaining these to me i will be able to complete the rest.
