Understanding the Quotient Property of Square Roots

The video tutorial covers the quotient property of square roots, explaining how to express the square root of a fraction as separate square roots of the numerator and denominator. It demonstrates the application of this property through examples, including factoring and simplifying numbers. The tutorial also addresses the need to rationalize the denominator, providing a step-by-step guide on how to achieve this. The session concludes with a practical demonstration using a calculator to verify the results.

What does the quotient property of square roots allow you to do with a fraction under a square root?

• Express it as a single square root.

• Express it as separate square roots of the numerator and denominator.

• Express it as a cube root.

• Express it as a logarithm.

In the example given, what are the numbers under the square roots for the numerator and denominator?

• 56 and 45

• 45 and 56

• 9 and 4

• 14 and 5

What is the first step in applying the quotient property to a fraction?

• Factoring the numbers

• Rationalizing the denominator

• Multiplying the numerator and denominator

• Expressing the square root of the fraction as separate square roots
