Let f(n) be the base-10 logarithm of the sum of the elements of the nth row in Pascal's triangle. Express $$\frac{f(n)}{\log 2}$$in terms of n.

Here's my best attempt

The sum of the elements on row n of Pascal's triangle  = 2^n

So....in  base 10, we have

Log 2^n  =

n Log 2  =  f(n)

And

f(n) / log 2   =

n log 2  / log 2  =

n
