I'm certain I'm missing something obvious .. again.
I'm having trouble solving the following (using a pen and paper approach)
[tex] \frac{ 3^{12} - 3^{10} }{ 3^{11} + 3^{10} } [/tex]
I've tried logarithms (I've only covered those with base 10 so far, so any log_n approach is disqualified), messing around with the exponents, roots and factoring, but I can't seem to find a way to do this without actually calculating the individual values.
Enlighten me, please.
