1Powers & Exponents
2The Structural Procedure
- Base is the factor being multiplied repeatedly
- Exponent tells how many times to multiply the base by itself
- Evaluate: 2³ = 2 × 2 × 2 = 8 (not 2 × 3 = 6)
3Mathematical Word Bank
- Powers and Exponents (Potencias y exponentes) — A power uses a base and an exponent to show repeated multiplication.
- Exponent (Exponente) — A small number that tells how many times to multiply a number by itself.
- Base (Base) — The number that gets multiplied by itself.
- Power (Potencia) — A number written with a base and an exponent, like 2³.
- Evaluate (Evaluar) — To find the value by putting numbers in for the letters.
4Watch out
- A common mistake in Powers and Exponents is multiplying the base by the exponent instead of using the base as a repeated factor — for example, thinking 2³ = 2 × 3 = 6 instead of 2³ = 2 × 2 × 2 = 8. Before you submit, rewrite the power as repeated multiplication first, then multiply step by step.

1 MULTIPLE CHOICE
(Lesson 6.1) A shelf is 5 feet long. Books are each 1/4 foot wide. How many books fit on the shelf? Which expression represents this?
- A5 ÷ 1/4 = 20 books
- B5 × 1/4 = 1 1/4 books
- C1/4 ÷ 5 = 1/20 book
