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.

Please help fast!

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

 

cool cool cool
