Hi! I was wondering what the best way to plug in would be for “example 1” in the “exponents and exponential functions” chapter?

Well, it wouldn’t really be practical without a calculator but because you’re allowed one on this question, you just pick numbers for *x* and *y* and then use those to get values for *m* and *n*. Say *x* = 2 and *y* = 3. Then:

Raise that to the –1 power again to get and you’re set:

Now just plug those values into the answer choices to see which one gives you *xy* = (2)(3) = 6.
