Short explanation
[Foundation and Higher] Calculate with roots and integer indices. is assessed within Structure and calculation. Roots and integer indices test powers, inverse operations and index laws, including negative or zero powers where they appear. A correct solution applies the relevant index law, simplifies powers or roots, and keeps each manipulation mathematically legal. This differs from exact pi or fraction arithmetic because the structure comes from powers and roots, not from preserving a multiple of pi. For exam answers, show the chosen representation, calculation step or graph reading before giving the final value.
