    solving for t....

    solve N(t)=N(base 0)(2)^t/d

    now seeing as there is...well really three variables,your not going to get a solid answer for t are you? and what exactly does it mean with the N with the zero below it,listed as a base,wouldn't it be a subscript?

    N = N_02^{t/d}

    \Rightarrow \frac N{N_0} = 2^{t/d}

    \Rightarrow \log_2 \frac N{N_0} = \frac td

    \Rightarrow t = d \cdot \log_2 \frac N{N_0}
