Thank you-could you look at my new post-I just needed clarification about f(x) = logx you said this would be true but doesn't it need parentheses or a separation between log and x for this to be correct? Thank you

I just noticed something-I had asked about if f(x) = 1/x is an exponential function and I think you rewrote it as f(x) = x^-1. Therefore, f(x) = 1/x is NOT an exponential function, correct?

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 =...

Please give me some direction for the above problem Thank you

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
