Video Solution

Solution Steps

00:00 Solve the following problem
00:03 The root of a fraction (A divided by B)
00:06 Equals the root of the numerator (A) divided by the root of the denominator (B)
00:11 Apply this formula to our exercise
00:15 Break down 64 to 8 squared
00:20 Break down 4 to 2 squared
00:24 The root of any number (A) squared cancels out the square
00:27 Apply this formula to our exercise and proceed to cancel out the square
00:35 This is the solution

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.
