Homework Help: Algebra

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

-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
