I'm reviewing for my final exam so one of the practice problems is: 5= 3^(x+5) Here's my attempt at it: ln 5= x+5 ln 3 ln 5 / ln 3 = x+5 (ln 5 / ln 3)-5= x 1.46-5 ≈ x -3.54 ≈ x I checked my answer and I get 3^1.46 ≈ 4.97 so rounding it up gives me 5 since I rounded off 1.46. However when I plug this equation into Mathway it gives me an answer of -3.39. I tried figuring out why (I know if you pay a fee you can view their steps, but I don't have the money at the moment) and eventually came to the conclusion that this is how they did it: 5= 3^(x+5) x+5 = ln 5 x = ln 5 - 5 x ≈ -3.39 But when I check their answer I get 3^1.61 ≈ 5.86 I think Mathway is wrong, but maybe I'm missing something. Which method is the correct one for solving this equation? Thanks for any help I receive.
