Homework Help: Algebra-Reiny please explain this

Posted by Anna on Monday, December 13, 2010 at 10:31pm.

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 get to the power of 2 and =4 became =8
x+1 = 8^4
x= 4095

Thank you
