Step-by-step solution

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

  • Simplify the numerator by multiplying the square roots together.
  • Simplify the denominator by recognizing that 2×2\sqrt{2} \times \sqrt{2} equals 2.
  • Apply the quotient rule for square roots to simplify the expression.

Now, let's work through each step:
Step 1: The numerator is 1243\sqrt{12} \cdot \sqrt{4} \cdot \sqrt{3}. Using the product property, combine them into one square root:
12×4×3=144\sqrt{12 \times 4 \times 3} = \sqrt{144}.

Step 2: The denominator is 22=4=2\sqrt{2} \cdot \sqrt{2} = \sqrt{4} = 2.

Step 3: Now apply the quotient rule:
1442=1444=36\frac{\sqrt{144}}{2} = \sqrt{\frac{144}{4}} = \sqrt{36}.

The result of 36\sqrt{36} is 6.

Therefore, the solution to the problem is 66.
