hey i need some help with a couple of questions please.....

change all bases to 2 then simplify fully

2^n x 4^n+1

8^n-2

(note that i cannot put the division line thingo in)

prove that:

a^m/n = n(outside radical sign)a^m (inside radical sign)

i dont know if you can understand that??? if not i will post a link 2 a word doc...

thanx 4 ur help!! :):)

I have a feeling you meant to type

2^n x 4^(n+1) or else the +1 would be a nuisance dangling term

change the last factor

4^(n+1) into [2^2]^(n+1) = 2^(2n+2)

so now you have

(2^n)(2^(2n+2))

= 2^(3n+2)

thanx,

actually the site cut off my question, what i tried to type was

2^n x 4^(n+1)

/

8^(n-2)
