The value of lim(x to oo ) (x-x^(2)log(...

The value of `lim_(x to oo ) (x-x^(2)log_(e)(1+(1)/(x)))` is _______.

A

1

B

`(1)/(2)`

C

`(1)/(4)`

D

2

Text Solution

Verified by Experts

The correct Answer is:
`(0.5)`
Let` x=1//y`
`:." "underset(xtooo)lim(x-x^(2)log_(e)(1+(1)/(x)))=underset(yto0)lim((1)/(y)-(log_(e)(1+y))/(y^(2)))`
`=underset(yto0)lim((y-log_(e)(1+y))/(y^(2)))`
`=underset(yto0)lim((y-(y-(y^(2))/(2)))/(y^(2)))=1//2`
