What is the product property of square roots?

Back

The product property states that √(a * b) = √a * √b for any non-negative numbers a and b.

Front

What is the quotient property of square roots?

Back

The quotient property states that √(a / b) = √a / √b for any non-negative numbers a and b, where b ≠ 0.
