Question: -5^(n-7) -2=-3 Answer: -log5^(16+5)/7... How?

Answer 1

-5^(n-7) -2=-3
5^(n-7) +2=3
5^(n-7) =1
log( 5^(n-7) ) = log(1)
(n-7) * log(5) = log(1)
(n-7) * log(5) = 0
n-7 = 0
n=7

Answer 2

Thank you but that wasn't the answer listed on the HW. The answer was: (-log5)16+5 all divided by 7

Answer 3

Well, then your answer has to be incorrect. I have no idea, how (-log5)16+5 / 7 would be the solution..

Answer 4

I'll double check. Thank you though :)
