Oh ok. So you know that you must find 7•7•7= to find your answer?

anonymous · Answer

but a "-" sign in bewteen those two numbers...

anonymous · Answer

So is it like $$7^{-3}$$

yesh...

anonymous · Answer

so you know that 7^3 equals 343, correct?

anonymous · Answer

Well you are going the opposite direction so it would be $$\frac{ 1 }{ 343 }$$
