    As you say

    [tex]\log _2 t = \frac{{\ln t}}{{\ln 2}}[/tex]

    So

    [tex]\int {\log _2 tdt = } \int {\frac{{\ln t}}{{\ln 2}}} dt = \frac{1}{{\ln 2}}\int {\ln tdt} [/tex]

    So now it's just integrating ln(t)dt. If you don't remember how, think integration by parts with f = lnt and dg = dt.
