An exponent counts copies being multiplied — 2³ = 2×2×2 = 8, never 2×3. A letter stands for a number, and an expression is a recipe for computing with it: exponents first, then × and ÷, then + and −. Two expressions are equivalent only if they match for EVERY value of the variable — one lucky match proves nothing.
