Problem 73

a. The Product Property of Square Roots states that the square root of a product is equal to the product of the square roots of each factor. For real numbers, \(a\) and \(b\) must be non-negative (\(a \geq 0, b \geq 0\)) to avoid imaginary numbers in the real number system.
b. The Quotient Property of Square Roots states that the square root of a quotient is equal to the quotient of the square roots of the numerator and denominator. Here, \(a \geq 0\) (to keep the numerator's square root real) and \(b > 0\) (to avoid division by zero and a negative denominator under the root).
c. Both properties relate square roots to operations (multiplication/division) inside vs. outside the root, require non-negative values for the radicands (with an extra non-zero rule for the quotient's denominator), and work to rewrite radical expressions into simpler forms.

Step1: Rewrite radical as rational exponent

$\sqrt[4]{16m^{32}} = (16m^{32})^{\frac{1}{4}}$

Step2: Distribute exponent to each factor

$= 16^{\frac{1}{4}} \cdot (m^{32})^{\frac{1}{4}}$

Step3: Simplify each term

$= 2 \cdot m^{8}$

Step1: Rewrite radicals as rational exponents

$(\sqrt{x})(\sqrt[3]{x}) = x^{\frac{1}{2}} \cdot x^{\frac{1}{3}}$

Step2: Add exponents (product rule)

$= x^{\frac{1}{2} + \frac{1}{3}} = x^{\frac{5}{6}}$

Step3: Rewrite as radical

$= \sqrt[6]{x^5}$

Step1: Rewrite radicals as rational exponents

$\sqrt[3]{\sqrt{b}} = (b^{\frac{1}{2}})^{\frac{1}{3}}$

Step2: Multiply exponents (power rule)

$= b^{\frac{1}{2} \cdot \frac{1}{3}} = b^{\frac{1}{6}}$

Step3: Rewrite as radical

$= \sqrt[6]{b}$

Step1: Create a sample problem

Simplify the expression: $\sqrt{12x^2} \cdot \sqrt{3x}$

Step2: Apply Product Property

$= \sqrt{12x^2 \cdot 3x} = \sqrt{36x^3}$

Step3: Simplify the radical

$= \sqrt{36} \cdot \sqrt{x^2} \cdot \sqrt{x} = 6x\sqrt{x}$

Answer:

a. The property: $\sqrt{ab} = \sqrt{a} \cdot \sqrt{b}$; limitations: $a \geq 0, b \geq 0$.
b. The property: $\sqrt{\frac{a}{b}} = \frac{\sqrt{a}}{\sqrt{b}}$; limitations: $a \geq 0, b > 0$.
c. Both link roots to arithmetic operations, require non-negative radicands, and simplify radicals.
