Question

What is the solution to the equation below?

log7+log(x-4)=1
Ox---
38
O x--18
OX=
OX=
18
3998

Answer 1

So, the solution to the equation

log(7)+log(x−4)=log(7)+log(x−4)=1 is x=38/7

​

, which is approximately 5.43 when rounded to two decimal places.

None of the options provided (38, -18, 18, 3998) match this solution.
