Are you trying to say..

**2 to power of 6 divide by 3 and..**

**4 to the power of minus 3 **

If yes this is how I've been taught to do it..

**First Question**

1) Calculate the answer of 2 to the power of 6

this is the same as saying 2x2x2x2x2x2 = 64

2) Then you divide 64 by 3

3) Giving you an answer of 64/3 or 21.3 recurring

**Second Question**

1) Calculate what 4 to the power of -3 is

2) When you have a minus.. you always write it as 1/4 ^3 (*The reciprocal) *

3) So you work out what is 4^ 3.. this is 4x4x4 = 64

4) Therefore, the answer would be 1/64

Hope that helps.. sorry if its confusing.. I need the maths symbols. to show you properly

Thanks this helped loads! :)

And for the first question it was written as a fraction so the 2^6 is over 3, so would i still have the same answer as yyou got?

I just realised that; i had a question in a past paper that asked me to show why 4^3/2 = 8

so i did 4^3 and got 64 then because the answer was 8 I knew to square root 64 not divide it by 2

So about the first question i asked, you would have to cube root 64 not divide by 3?Wouldn't you?
