Step-by-Step Solution

To solve the expression 246\sqrt{\frac{2}{4}} \cdot \sqrt{6}, we will break it down and simplify step by step.

Step 1: Simplify the square root of the fraction.
24\sqrt{\frac{2}{4}} can be rewritten using the square root of a quotient property:
24=24\sqrt{\frac{2}{4}} = \frac{\sqrt{2}}{\sqrt{4}}.

Step 2: Simplify 4\sqrt{4}.
Since 4=2\sqrt{4} = 2, the expression becomes:
22\frac{\sqrt{2}}{2}.

Step 3: Multiply by 6\sqrt{6}.
Now multiply 22\frac{\sqrt{2}}{2} by 6\sqrt{6}:
226=262\frac{\sqrt{2}}{2} \cdot \sqrt{6} = \frac{\sqrt{2 \cdot 6}}{2}.

Step 4: Simplify the square root.
The multiplication inside the square root becomes 12\sqrt{12}, so:
122\frac{\sqrt{12}}{2}.

Step 5: Simplify 12\sqrt{12}.
Since 12=43=43=23\sqrt{12} = \sqrt{4 \cdot 3} = \sqrt{4} \cdot \sqrt{3} = 2\sqrt{3},
this results in 232=3\frac{2\sqrt{3}}{2} = \sqrt{3}.

Therefore, the solution to the problem is 3\sqrt{3}.

Answer

3 \sqrt{3}
