Any help would be appreciated. problem: 4^2x - 4^x = 8 * 4^(x+3) solve for x Lets assume the equation is: or: rearrange: so either which is impossible or: and you should be able to finish this yourself from that.

thanks a lot to all of you. I think I've been everything except this solution, thank you for opening my eyes!!
