Question 242094: I need help on how to solve a logarithmic Equation. The question is
3 Log (base 2) x+1 = 7
When I tried putting this equation into exponential form, I got

2^7 = (x+1)^3. However, when I solved for this, I did not end up with
the answer that is needed. I ended up looking up the answer in the back of the book so that i could see if i could backtrack from there, but it was simply 4.
