When doing this problem, we have the variable in the base and the exponent. So we're going to take E to the lane of X to the -5 / l and X. The limit as X goes to zero from the right hand side. So we can bring the E out as a base and just look at the limit as X goes to zero from the right of the exponent. We're going to use the power rule to bring down that -5 lane X times lane X. The lane X's here are actually going to cancel, so we're going to get E limit as X goes to zero from the right of -5 There is no X there. So we can now see that that's really just -5. So we get E to the -5 or 1 / E to the 5th.
