1. This may seem simple but my head wont get around it so
1. Write 9^3 x 27^2 as a single power of 3
2. Write 8^6 / 4^3 x 2^5 as a single power of 2

2. Bit late for maths?
Well for these questions, to simplify them you need a common base. So work out what 9 is in terms of 3 and how that can apply to your problem, using rules of indices. Then do the same for the 27, and use the other indice rule where you multiply two together
3. Probably didn't make any sense but I'm tired aha
4. yeah for the first one you basically have to do:

9^3 = (3^2)^3
27^2 = (3^3)^2

so you do:

(3^2)^3 x (3^3)^2
= 3^12
