Where [answer] is just the final number or expression that solves the problem.

Problem: Let $f(n)$ be the base-10 logarithm of the sum of the elements of the $n$th row in Pascal's triangle. Express $\frac{f(n)}{\log_{10} 2}$ in terms of $n$. Recall that Pascal's triangle begins

\begin{tabular}{rccccccccc}
$n=0$:& & & & & 1\\\noalign{\smallskip\smallskip}
$n=1$:& & & & 1 & & 1\\\noalign{\smallskip\smallskip}
$n=2$:& & & 1 & & 2 & & 1\\\noalign{\smallskip\smallskip}
$n=3$:& & 1 & & 3 & & 3 & & 1\\\noalign{\smallskip\smallskip}
$n=4$:& 1 & & 4 & & 6 & & 4 & & 1\\\noalign{\smallskip\smallskip}
& & & & & $\vdots$ & & & &
