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=(-3125)/(3) =-1041.66`
