उत्तर

Let I = `int log (1 + x)^((1 + x)).dx`

= `int (1 + x)log(1 + x).dx`

= `int [log(1 + x)] (1 + x).dx`

= `[log(1 + x) int (1 + x).dx - int[d/dt {log(1 + x)} int (1 + x).dx].dx`

= `[log (1 + x)] [(1 + x)^2/2] - int 1/(x + 1).(x + 1)^2/(2).dx`

= `(x + 1)^2/(2).log(1 + x) - (1)/(2) int (x + 1).dx`

= `(x + 1)^2/(2).log (1 + x) - (1)/(2).(x + 1)^2/(2) + c`

= `(x + 1)^2/(2)[log (1 + x) - 1/2] + c`.
