Answer 1

\[\Large \frac{(96^2)(81^2)}{(216^3)}\] Is this your qeustion?

Answer 2

Yup

Answer 3

Is 6 the answer? I'm not supposed to use a calculator, but I did.

Answer 4

So how do I do this without a calculator?

Answer 5

With cancellations. But factor everything out first.... (prime factors would be nice, btw)

Answer 6

Yes first you should factor it out

Answer 7

So this is basically a problem about division by hand?

Answer 8

Basically, but sometimes you can have varaibles like a^-3/a^2 so this helps.

Answer 9

OK. Should I try to divide everything by 3 first? Or is there a better prime number to try?

Answer 10

You might want to try to do this first \[\Large at~the~topp~~is~(96^2)(81^2)=(81*96)^2\]

Answer 11

Bottom is just 216^3

Answer 12

\[\Large \frac{(96 \times 81)^2}{(216^3)}\]
