Note you can write "log base 2 of x" as "log(2,x)", or, better yet, "log(2,(x))".
[write the constant 3 as log base 2 of something]
[rules of logarithms: difference of logs = log of quotient; log(x^n) = n*log(x)]
[if the logs of the expressions are equal, then the expressions are equal]
or
Both solutions satisfy the original equation, so both are solutions.
