Math Problem Statement

Simplify fully: \(\frac{\sqrt{60}}{\sqrt{5}}\)

Solution

The problem asks to simplify the expression 605\frac{\sqrt{60}}{\sqrt{5}}. Here's how to solve it step by step:

Step 1: Apply the quotient rule for square roots

The quotient rule states that ab=ab\frac{\sqrt{a}}{\sqrt{b}} = \sqrt{\frac{a}{b}}. Applying this rule, we have: 605=605\frac{\sqrt{60}}{\sqrt{5}} = \sqrt{\frac{60}{5}}

Step 2: Simplify the fraction under the square root

605=12\frac{60}{5} = 12 So the expression becomes: 12\sqrt{12}

Step 3: Simplify 12\sqrt{12}

Break 12 into its prime factors: 12=4312 = 4 \cdot 3 Since 4 is a perfect square, we can simplify: 12=43=43=23\sqrt{12} = \sqrt{4 \cdot 3} = \sqrt{4} \cdot \sqrt{3} = 2\sqrt{3}

Final Answer:

605=23\frac{\sqrt{60}}{\sqrt{5}} = 2\sqrt{3}
