Question

log(x+5)-log(x-3)=log5
want to get checked!
logx-3/x+5=log5
drop the log .
x-3/x+5=5
(x+5)*(x-3/x+5)=5(x+5)
x-3=5x+25
-28=4x
x=-7

Answer 1

consider - to be under

Answer 2

- log(n) = /n in the setup

Answer 3

logx-3/x+5=log5
Is this step correct?

Answer 4

Just check it by inputting the following into the calculator.

\( \color{Black}{\Rightarrow (\log (-7) + 5) - (\log(-7) - 3)}\) and \(\log5\)

Check if they give the same result.

Answer 5

I think it should have been logx+5/x-3=log5

Answer 6

make sure it's non negative too.

Answer 7

\( \color{Black}{\Rightarrow \log(-2) - \log(-10) = ?}\)

Answer 8

Doesn't look like we have a definite number ;)
