Ln function

Solve for x

x=2.6e^(.1.2) + 1.8e^(2.9)

do I divide the 2.6 and 1.8 bring to the other side, so I can bring the exponents infront of the e??

I am not quite sure on this one. Any help would be great, thanks.

It seems like you already have the answer to solve for x. You already have x as a constant number. What do you want to solve?

I have to solve for x and have to use the Ln function to get it.

I am a bit lost on this. - December 4th 2010, 12:17 PMbradycat
I got it I think I got confused on something. My teacher does not explain well enough, so my notes reflect that.

I got an answer of 33.497 for x - December 4th 2010, 12:59 PMmathemagister
If you meant (-1.2) instead of (.1.2), you're right!

Yes it was -1.2 THANKS ALOT for the help. Really appreciate it. Makes things clearer.
