Question 682776: How do you solve 8^4x-1=7^-x? I cannot use the calculator for this, I must show my work. I have been trying to solve for 3 days... Answer by solver91311(24713) (Show Source):
With two different (and relatively prime) bases you are pretty much stuck with numerical analysis, and for that you had better have a calculator. Sorry, that's the best I can do.
