The primitive of the function f(x)=(1-...

The primitive of the function `f(x)=(1-1/(x^2))a^(x+1/x)\ ,\ a >0` is
(a)`(a^(x+1/x))/((log)_e a)`
(b) `(log)_e adota^(x+1/x)`
(c) `(a^(x+1/x))/x(log)_e a`
(d) `x(a^(x+1/x))/((log)_e a)`

A

`(a^(x^+(1)/(x)))/(log_(e)a)`

B

`a^(x+(1)/(x))log_(e)a`

C

`a^(x+(1)/(x))/(x)log_(e)a`

D

`a^(x+(1)/(x))/(log_(e)a)`

Text Solution

Verified by Experts

The correct Answer is:
A
The primitive of f (x) is
`int(1-(1)/(x^(2)))a^(x+(1)/(x))dx = int (x+(1)/(x))=(a^(x+(1)/(x)))/(log_(e)a)+C`
