If f : R 
Ris a function defined as f(x 3 ) = x 5 , 
- {0} and f (x) is differentiate 
, then the value of 
is equal to (here f' represents the derivative of f)
Text Solution
Verified by ExpertsThe correct answer is:
3
3.75
f(x 3 ) = x 5
On differentiating with respect to x
f'(x 3 ) . 3x 2 = 5 . x 4
Putting x = 3, we get,
f' (27) = 
(9) = 15
