    How do I start to solve -2log8(x+1) = -8? I think -2log8(x+1) is log8^(x+1)to the 2nd but then what do I do because then I think I should do log-8/log8 = x+1)^2 but that doesn't work at all Thank you for any help you can give

    Solve the equation : 8^2x-1 = 16^x+1 i know you have to log both sides log8^2x-1 = log16^x+1 and then you use the exponential rule 2x-1 log8 = x+1 log16 but then i don't know what to do...

    Hi Reiny, I posted this problem earlier and you responded but I don't get the reasoning- The problem was -2log8(x+1) = -8 you said multiply by -2 and then you put log8(x+1)=4(wasn't that dividing by -2) log8(x+1)^2 = 8 (how did
