The value of e^ x (x⁵+5 x⁴+1 ) d x is
Options
- Ae^ x x⁵+e^ x +C
- Be^ x x⁵
- C5 x⁴ e^ x
- De^ x+1 x⁵+C
Correct answer
A. e^ x x⁵+e^ x +C
Step-by-step solution
Let aligned &I= e^ x (x⁵+5 x⁴+1 ) d x &= e_ I I ^ x (x⁵+1 ) d x+ e^ x (5 x⁴ ) d x aligned = (x⁵+1 ) e^ x d x- [ ( e^ x d x ) d d x x⁵+1 ) ] d x + e^ x (5 x⁴ ) d x = x⁵+1 ) e^ x - e^ x (5 x⁴ ) d x+ e^ x (5 x⁴ ) d x = (x⁵+1 ) e^ x +C=e^ x x⁵+e^ * +C
