Question

log₅(4x+1)-log₅(x-5)=2
x=_____?

Answer 1

in this similar problem, x=6
log(2)(x+2)+log(2)(x-4)=4

Answer 2

When you have the same base (in this case it is 5) you can just cross out the logs. Then solve (4x+1)(x-5)=2

Answer 3

okay, then I get 6/5... that doesn't look right?

Answer 4

oh, it would be (4x+1)(X-5)=2^5 I believe sorry
been a while since I have done logs

Answer 5

Or it's =5^2 :p

Answer 6

oh, thanks!

Answer 7

np, look up Log rules on google, there are a bunch and they saved me in trig :P

Answer 8

eek, the answer was 6 again!
