Your subject line says that you need to "solve using induction", but induction is a form of proof, not of solution. You can learn about what induction is, and how to apply it, in this lesson.n! < ((n+1)/2)^n if n>2
What you wrote means this:if I have 4e^2x + 5e^3x = 15
how do I solve for x?
How did you get to this step?I tried ln 4 +2x+ln5+3x=ln 15 but that doesn't work.
