What is the solution of log3x + 4125 = 3?

If we take it as:

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

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

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)
