Step-by-step solution

To solve this problem, we'll follow these steps:

  • Step 1: Simplify the fraction 644\frac{64}{4}.
  • Step 2: Apply the Square Root Quotient Property.
  • Step 3: Calculate the square roots of the numerator and the denominator.

Now, let's work through each step:

Step 1: Simplify the fraction 644\frac{64}{4}. The division yields 1616, so we have 16\sqrt{16}.

Step 2: Using the Square Root Quotient Property, 644=644\sqrt{\frac{64}{4}} = \frac{\sqrt{64}}{\sqrt{4}}.

Step 3: Calculate the square roots: 64=8\sqrt{64} = 8 and 4=2\sqrt{4} = 2, so 82=4\frac{8}{2} = 4.

Thus, the solution to the problem is 644=4\sqrt{\frac{64}{4}} = 4.

Therefore, the correct answer is 44, which corresponds to choice 3 in the given options.
