put it this way:

(2 x 2^5) x ( 3 x 3^7) = 2^n x 3^m

can you do it now? - Nov 19th 2009, 07:53 AMandyboy179

your bracket is misleading that all.

read it like this (2 x 3^7) x ( 3 x 2^5) = 2 x 3^7 x 3 x 2^5 right?

then rearrange a bit 2 x 3^7 x 3 x 2^5 = 2 x 2^5 x 3 x 3^7

you can add the brackets in if you want then. - Nov 19th 2009, 08:01 AMandyboy179

2 x 2^5 = 2^6

3 x 3^7 = 3^8

so n=6

and m=8

think of it as 2 x (2x2x2x2x2) and 3 x (3x3x3x3x3x3x3) - Nov 19th 2009, 08:19 AMandyboy179
