Answer 3

yes, the dot is multiply - sorry!

Answer 4

((15^(2)n)(25^(n))(4))/(45^(n))

((225n*25^(n))(4))/(45^(n))

(4(225n*25^(n)))/(45^(n))

(225n((5)/(9))^(n))

Answer 7

Sam, thanks but your answer does not correspond with the model answer. I know they're looking for something to do with prime numbers. The model answer is:
3^4n / 2^n
I just don't know how to get there - any idea?

Answer 8

I think the question you written is wrong, can you draw it?
