Integration of

\frac{1}{{\sqrt {{x^2} + \,\,9} }}

with respect to

\left( {{x^2} + \,\,1} \right)

is equal to

View answer and explanation

Correct option: C

2\,\sqrt {{x^2} + \,\,9} \,\, + \,\,C

The correct answer is C (

2\\,\sqrt {{{{x^2} + \,\,9}}} \,\, + \,\,C

) because the integral is solved by recognizing the differential and integrating.
