Laws of Exponents Product Rule

Laws of exponents - Power of a Product Rule

by J. Gomez

Power of Product Shortcut?!!

Instead of repeating it three times you can just distribute the exponent to everything inside the group.

(x²y)⁵ = x^2*5 y^1*5 = x¹⁰y⁵

Further Example

• Now lets combine power of a product with power of a power

• We know that if we have a power outside the parenthesis we distribute it to everything inside the parenthesis.

• We also know that if we distribute a power to another power we multiply these powers.

Multiple Choice

Simplify the following expression:

(3y⁴)²

• 9y⁸

• 9y⁶
