Multiplying Radical Expressions
Multiply radical expressions in Grade 9 Algebra using the product property. Multiply coefficients together and radicands together, then simplify the result.
Key Concepts
New Concept The square root of a product equals the product of the square roots of the factors. $$ \sqrt{ab} = \sqrt{a} \cdot \sqrt{b} \text{ where } a \ge 0 \text{ and } b \ge 0 $$ What’s next Next, you’ll apply this rule to simplify products and multiply more complex expressions involving radicals, like binomials.
