1.	If f(x) is a polynomial function such that f(x)⋅f(1x)=f(x)+f(1x) such that f(4)=65, then sum of binomial coefficients in the expansion of (1+x)f(2) is
Answer» If $f (x)$ is a polynomial function such that $f (x) \cdot f (\frac{1}{x}) = f (x) + f (\frac{1}{x})$ such that $f (4) = 65$ , then sum of binomial coefficients in the expansion of $(1 + x)^{f (2)}$ is
