| Topic | Indefinite & Definite Integrals |
| Type | Basic indefinite integration |
| Difficulty | Easy -1.2 This is a straightforward integration question requiring only the power rule applied to three terms. It's routine practice with no problem-solving element—students simply recall and apply ∫x^n dx = x^(n+1)/(n+1) + c, including converting the root to fractional index form. Worth 5 marks only because of the three separate terms to integrate. |
