Author note — to cover
Applying one index across a product and across a quotient: (2 x 5) cubed and (3/4) squared, numeric bases only; combining with earlier laws in one simplification. Teach before negative-index-of-a-fraction, which uses the quotient case. Algebraic brackets like (2x cubed) squared live in Algebra. Both tiers. (N7)
