\int \frac{\left\{x+\sqrt{x^2+1}\right\}^n}{\sqrt{x^2+1}} d x

is equal to

View answer and explanation

Correct option: B

\frac{1}{n}\left\{x+\sqrt{x^2+1}\right\}^n+C

Option B is correct. The integral is solved by recognizing that the derivative of

x + \sqrt{x^2 + 1}

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

, allowing for a direct substitution and integration.
