Step-by-Step Solution

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

  • Step 1: Calculate the value of each expression under the square root.
  • Step 2: Simplify the square roots to find their numerical values.
  • Step 3: Compare the results to find the largest value.

Now, let's work through each step:

Step 1: Calculate the values under each square root.

  • For choice 1: 255=5 \frac{25}{5} = 5
  • For choice 2: 366=6 \frac{36}{6} = 6
  • For choice 3: 369=4 \frac{36}{9} = 4
  • For choice 4: 84=2 \frac{8}{4} = 2

Step 2: Compute the square roots.

  • Choice 1: 52.236 \sqrt{5} \approx 2.236
  • Choice 2: 62.449 \sqrt{6} \approx 2.449
  • Choice 3: 4=2 \sqrt{4} = 2
  • Choice 4: 21.414 \sqrt{2} \approx 1.414

Step 3: Compare the square roots calculated.

The largest value among the choices is found in choice 2:

366=62.449 \sqrt{\frac{36}{6}} = \sqrt{6} \approx 2.449 is larger than the other evaluated square roots.

Therefore, the largest value is given by the expression 366 \sqrt{\frac{36}{6}} .

Answer

255 \sqrt{\frac{25}{5}}
