Multiplying powers with the same base

2. Product of powers, numeric base, variable base
To multiply powers with the same base, keep the base and add the exponents. aᵐ • aᴺ = aᵐ⁺ᴺ , where a ≠ 0 and m and n are integers. 9⁴ • 9² = 9⁶ = 531,441 x² • x⁶ = x⁸

3. Examples
Together 1. 3² • 3⁴ 2. n⁷ • n² 3. 2² • 2¯⁷ • 2³ 4. p¯² z • p z³

4. Examples
On Your Own a. y⁴ • y² • y¯² b. 4¯⁴ • 4⁴ c. 6² • 6⁵ d. a² m⁵ • a¯⁷m

6. Product of powers variable bases with coefficients
To multiply powers with the same base and a coefficient, multiply the coefficients, keep the base and add the exponents. 2aᵐ • 3aᴺ = 6aᵐ⁺ᴺ , where a ≠ 0 and m and n are integers. 3k⁴ • 4k⁵ = 12k⁹
