| Topic | Indefinite & Definite Integrals |
| Type | Pure definite integration |
| Difficulty | Moderate -0.8 This is a straightforward C2 integration question requiring only basic power rule application to polynomial and root terms, followed by substitution of limits. It's easier than average as it involves no algebraic manipulation, no integration techniques beyond the power rule, and the arithmetic is simple with convenient limits. |
