Solving Logarithmic Equations Help. Any Aid Appreciated
This forum provides such excellent help that I am back. :D
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! :D
