The Anatomy of a Power

BASE
The number being multiplied
EXPONENT
How many times to multiply
"\(x\) to the power of \(n\)"
1. PRODUCT RULE
Regla del Producto
\(x^a \cdot x^b = x^{a+b}\)
The Rule
If the bases are the same, ADD the exponents.
Example
\(x^3 \cdot x^4 = ?\)
Think: (x·x·x) · (x·x·x·x)
\( = x^7\)
2. QUOTIENT RULE
Regla del Cociente
\(\frac{x^a}{x^b} = x^{a-b}\)
The Rule
If the bases are the same, SUBTRACT the exponents.
Example
\(\frac{x^{10}}{x^4} = ?\)
Think: Cancel out the extra factors
\( = x^6\)
3. POWER OF A POWER
Potencia de una Potencia
\((x^a)^b = x^{a \cdot b}\)
The Rule
When a power is raised to another power, MULTIPLY the exponents.
Example
\((y^2)^5 = ?\)
Think: \(y^2 \cdot y^2 \cdot y^2 \cdot y^2 \cdot y^2\)
\( = y^{10}\)
THE HERO RULE
\(x^0 = 1\)
Zero Exponent Rule
"Any base (except zero) raised to the zero power is always ONE."
\(5^0 = 1\)
\((-12)^0 = 1\)
\((xyz^4)^0 = 1\)

Power Play Teacher Guide TEACHER GUIDE
Power Play Mastery: Laws of Exponents
Lesson Objectives
Students will identify and apply the Product, Quotient, Power of a Power, and Zero Exponent rules.
Students will simplify algebraic expressions involving multiple exponent laws.
ESL learners will utilize bilingual vocabulary to bridge conceptual understanding.
Pacing & Strategy (Modified for Stations)
15m
Direct Instruction (Slides)
Focus on the bilingual word bank and "Anatomy of a Power." Prepare students for hands-on activities.
15m
Guided Notes (Foldable)
Construct the "Law Library" foldable. This will be their primary reference tool during the stations.
60m
Power Stations (Rotations)
Four stations, 15 minutes each. Use a visual timer. Rotations: Sort → Error Analysis → Maze → Application .
Station Answer Key
Station 2: Error Analysis
A: Added exponents instead of multiplying (or vice versa). Fix: \(x^7\)B: Divided exponents instead of subtracting. Fix: \(y^9\)C: Added exponents instead of multiplying. Fix: \(z^{12}\)
Station 3: Maze Path
Start → \(x^7\) → \(y^6\) → \(w^6\) → \(1\) → Finish
Station 4: Application
1. Area: \((x^3)^2 = x^6\). 2. Bacteria: \(2^{10} \cdot 2^5 = 2^{15}\)
ESL & Differentiation
• Strategic Grouping: Pair students with varying English proficiencies (L1 support).
• Visual Cues: Every station includes a Spanish translation of the title and key instructions.
• Scaffolded Station 4: The bacterical growth problem includes the formula \(2^{10} \cdot 2^5\) in the Spanish translation to ensure they know which rule to apply.

Rotate through each station when the timer sounds. Keep your station clean! If you finish early, help a teammate explain their answer in both English and Spanish.
Roten por cada estación cuando suene el cronómetro. ¡Mantengan su estación limpia! Si terminan temprano, ayuden a un compañero a explicar su respuesta.
