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

  • Algebra-Could Mathmate or Reiny or Dr. Bob look at this if you have time -

    Please give me some direction for the above problem
    Thank you

  • Algebra -

    -2log8(x+1) = -8
    first of all, multiply be -2
    log8(x+1) = 4
    log8(x+1)^2 = 8
    (x+1) = 8^4
    x = 4095

    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 you …
