Question
If f(x) = 
(x - n)n(101-n) ; then 
=
(x - n)n(101-n) ; then =Options
A.5050
B.
C.10010
D.
Solution
f(x) = (x - 1)100. (x - 2)2.99. (x - 3)3.98.....(x -100)100.1
Take log & than differentiate we get
Now
= 1 + 2 + 3 .... + 100 = 5050
∴
Take log & than differentiate we get
Now
= 1 + 2 + 3 .... + 100 = 5050∴
