There is this problem that I just can not begin to solve , this is a simultaneous equation. Can anyone help me solve this equation.
For example :
- Lessons : http://en.wikipedia.org/wiki/List_of...mic_identities
- Examples : http://people.hofstra.edu/Stefan_Wan...pic1/logs.html
- Exercises : [pick any suitable website for exercises]
and then I am stock right here. Did I do it OK so far? I want to add but I don't know if they both have to be the same base to do that. Could someone please help me with the working of this so that I can use it to solve the other problem like it in the book?
It's far simpler than you're making it out to be:
By the definition of a logarithm, .
Why? -- we know that . So and therefore .
Using this and the fact that for any , we get:
I believe you can solve that.
