thanks :) teehee .

Answer 4

In general, for any numbers a and b, a^-b = 1/ (a^b).

So if there's a negative exponent, move the whole thing to the denominator and make the exponent positive.

Answer 5

And I'm sure you DESPERATELY want to know why this work. Well, I'll gladly tell you.

If you know exponent rules, you know that (a^n) / (a^m) = a^(n-m).
Now if x is a negative number, then a^(-x) = a^(0-x) = (a^0) / (a^x) = 1/(a^x)
