Question

What is the solution of log3x + 4125 = 3?

Answer 1

log3 (x) + 4125=3 final answer

Answer 2

If we take it as:

$log (3x+4125)=3$

To solve this we have to understand the log this way:

$log_{b} a=c   <--> b^{c}=a$

and remember that when b is not shown it means it is 10. So:

$10^{3} =3x+4125\\1000-4125=3x\\x=\frac{-3125}{3} =-1041.66$
