Best ResponseYou've already chosen the best response.0so we want to go the other direction for negative exponents. to do this we have to do the inverse operation of multiplication. do you know what the inverse operation of multiplication is?

Best ResponseYou've already chosen the best response.0well, technically, we multiply by the reciprocal... but ususally people just call it division.

Best ResponseYou've already chosen the best response.0so if we are at \(7^3\) and we want to get to \(7^2\), we divide by 7 or multiply by 1/7... okay?

Best ResponseYou've already chosen the best response.0so let's take it a step further... let's figure out what \(7^0\) should be , using the pattern...

Best ResponseYou've already chosen the best response.0very good!!! now we use the pattern. to go down (negative direction) we divide by 7. what is 7 divided by 7?
