Question 408301
We wish to find {{{log(2, (log(3, 81)))}}}. Just work from the inside out: since {{{log(3, 81) = 4}}}, then this is equivalent to finding {{{log(2, 4)}}} which is equal to 2. Here, I already assumed you were familiar with finding log functions such as {{{log(3, 81)}}} since {{{3^4 = 81}}}.
