How do you solve the following equation:
3logbase(2)X+1=7
3log2(x)+1=7
log2(x^3)=6
x^3=2^6 (exponential form)
take cube root of both sides
x=2^2
x=4

There are two ways to interpret the problem as you rendered it.
You either meant:
the solution to which would make a fiend from the seventh circle of Hell look attractive, or you meant:
the solution to which is nice, neat, and only involves integers. I'm going for the simple way since, at this point, I have 51% of the vote.
Add -1 to both sides:
Multiply both sides by
Use the definition of the logarithm function
