Homework Statement
I tutor math for a couple of high school kids, and usually don't have any problems. Occasionally we run into a problem that takes me a minute, since I haven't actually used a lot of this stuff since I was in high school, but I always figure it out very quickly when that happens.
However, yesterday I came across a problem in the middle of a set of really straightforward logarithm problems, and I couldn't work out how to do it. It was a little embarassing, but I'm more curious than anything. How would one go about solving an equation like this?
30(1.4)[itex]^{x}[/itex] = 30 + 0.4x
Of course, the numbers aren't important, just the general layout, with an x in an exponent and in a term.
No matter how I work it, I can't seem to isolate the x. It seems like there must be some simple approach, especially since all of the other problems were so easy, but I can't think of it.
