\int \nolimits_0^\infty \,\,\left[ {\frac{{\left[ {x\,\, + \,\,1} \right]}}{{{e^x}}}} \right]\,\,dx

(where

\left[ {\,\, \cdot \,\,} \right]

denotes greatest integer function) is equal to

View answer and explanation

Correct option: A

\mathrm{0}

Option A (0) is correct because the expression inside the greatest integer function is always less than 1, making the greatest integer function equal to 0.
