Author note — to cover

Multiplying indices when raising a power to a power, e.g. (2 cubed) to the 4, explicitly contrasted with 2 cubed times 2 to the 4; combined-law simplifications with numeric bases. Justifies fractional indices later at Higher; algebraic versions live on the Algebra notation page. Both tiers. (N7)

• Fluency — direct questions on raising a power to a power, limited to this lesson's stated scope (4 questions).
• Application — use the same skill in unfamiliar or contextual questions without introducing a later method (4 questions).
• Check — questions built around the exclusions and likely misconceptions named in the lesson brief (4 questions).
