Hi everyone,

This forum provides such excellent help that I am back.

This time I am attempting to solve basic logarithmic equations. As I was working my way through the questions, a couple of them stumped me.

Here they are:

Solve for x:

1) 5 logx (625) = 10

2) -log3x -1 (1/32) = 5

So, x, and 3x -1 are the respective bases of the logarithm in the above examples. In the first question, I started by dividing both sides by "5" to get logx 625 = 2. And then I simplified to get 4 logx 5 = 2. I divided both sides by 4 again and achieved: logx 5 = 2/4 = 1/2

But from there I am not sure how to go. And I was on an utterly wrong tangent for question 2.

Any help at all will be much appreciated!

Thanks,

Nathaniel
