The indefinite integral ∫ e e x x e x ⋅ ln x + 1 x d x simplifies to (where, c is the constant of integration)
Options
- Ax ln ln x + c
- Be e x + c
- Ce e x x + c
- De e x ⋅ ln x + c
Correct answer
D. e e x ⋅ ln x + c
Step-by-step solution
Given integral is I = ∫ e e x ⋅ e x ⋅ ln ⁡ x + e e x x d x Let, e e x = f x and ln ⁡ x = g x ∴ I = ∫ f ' x g x + f x g ' x d x = f x · g x + c = e e x ⋅ ln ⁡ x + c
