# Thread: Solve the log function using graphing calculator

1. ## Solve the log function using graphing calculator

123x-1= 5982x-3

I need to simplify the equation first and then plug it into a calculator to solve for x. The problem is, I don't know how to simplify this type of equation with two exponents..help

2. ## Re: Solve the log function using graphing calculator

Oh, and how do I put in the numbers on a graphing calc if I want to find for example 3log2 ?

3. ## Re: Solve the log function using graphing calculator

$\log(12^{3x-1}) = \log(598^{2x-3})$

$(3x-1)\log{12} = (2x-3)\log{598}$

now graph ...

$y = (3x-1)\log{12} - (2x-3)\log{598}$

... and look for the zero.

4. ## Re: Solve the log function using graphing calculator

But the equation y=(3x-1)log12-(2x-3)log598 is not simplified ! It has to be simplified until it is in terms of x. how do i do that?

5. ## Re: Solve the log function using graphing calculator

the equation is in terms of x ... do you mean solve for x ?

6. ## Re: Solve the log function using graphing calculator

yes, that's what i mean. I mean I have to make the simplified equation look like x=something so that I can easily put it into the calculator. in our class we were told not to graph them on the graphing calc

7. ## Re: Solve the log function using graphing calculator

I'm not sure, but I think your equation was in terms of y instead.

8. ## Re: Solve the log function using graphing calculator

$(3x-1)\log{12} = (2x-3)\log{598}$

this is a linear equation ... you try solving for x. remember that $\log{12}$ and $\log{598}$ are just constants.
