Solution:
The Given function is : f(x)= 4 (7)2 x= 56 x →None of the option Matches.
But it appears like the function should be like this : f(x)= 4.7²x
Two functions are said to be Equivalent if they are written in different ways ,but the end result is same.
So, f(x)= (4 × 7× 7) x
= 196 x →→Option (C)
