convert everything to powers of 2 and 3

so the expression becomes:(2^6x3^3x2^4)/(2^10x3) which simplifies to 3^2 or 9

It's pretty simple.

8^2 x 3^3 x 2^4 = 2^6 * 2^4* 3^3 = 2^10 * 3^3 -- i
and 96^2 = (2^5 * 3) whole sq.--- ii

dividing i by ii

2^ 10 * 3^3
--------------- = 3^1 = 3
2^10 * 3^2

Hope it helps.
