Arrange in descending order -
`sqrt8-sqrt5,sqrt6-sqrt7,sqrt9-sqrt4,sqrt(11)-sqrt2,sqrt(10)-sqrt3`

Answer

To arrange the expressions \( \sqrt{8} - \sqrt{5}, \sqrt{6} - \sqrt{7}, \sqrt{9} - \sqrt{4}, \sqrt{11} - \sqrt{2}, \sqrt{10} - \sqrt{3} \) in descending order, we will first calculate the approximate values of each expression.

### Step 1: Calculate \( \sqrt{8} - \sqrt{5} \)
- \( \sqrt{8} \approx 2.828 \)
- \( \sqrt{5} \approx 2.236 \)
- \( \sqrt{8} - \sqrt{5} \approx 2.828 - 2.236 = 0.592 \)

### Step 2: Calculate \( \sqrt{6} - \sqrt{7} \)
- \( \sqrt{6} \approx 2.449 \)
- \( \sqrt{7} \approx 2.646 \)
- \( \sqrt{6} - \sqrt{7} \approx 2.449 - 2.646 = -0.197 \)

### Step 3: Calculate \( \sqrt{9} - \sqrt{4} \)
- \( \sqrt{9} = 3 \)
- \( \sqrt{4} = 2 \)
- \( \sqrt{9} - \sqrt{4} = 3 - 2 = 1 \)

### Step 4: Calculate \( \sqrt{11} - \sqrt{2} \)
- \( \sqrt{11} \approx 3.317 \)
- \( \sqrt{2} \approx 1.414 \)
- \( \sqrt{11} - \sqrt{2} \approx 3.317 - 1.414 = 1.903 \)

### Step 5: Calculate \( \sqrt{10} - \sqrt{3} \)
- \( \sqrt{10} \approx 3.162 \)
- \( \sqrt{3} \approx 1.732 \)
- \( \sqrt{10} - \sqrt{3} \approx 3.162 - 1.732 = 1.430 \)

### Step 6: List the calculated values
- \( \sqrt{8} - \sqrt{5} \approx 0.592 \)
- \( \sqrt{6} - \sqrt{7} \approx -0.197 \)
- \( \sqrt{9} - \sqrt{4} = 1 \)
- \( \sqrt{11} - \sqrt{2} \approx 1.903 \)
- \( \sqrt{10} - \sqrt{3} \approx 1.430 \)

### Step 7: Arrange in descending order
Now, we can arrange these values in descending order:
1. \( \sqrt{11} - \sqrt{2} \approx 1.903 \)
2. \( \sqrt{10} - \sqrt{3} \approx 1.430 \)
3. \( \sqrt{9} - \sqrt{4} = 1 \)
4. \( \sqrt{8} - \sqrt{5} \approx 0.592 \)
5. \( \sqrt{6} - \sqrt{7} \approx -0.197 \)

### Final Answer
The expressions arranged in descending order are:
1. \( \sqrt{11} - \sqrt{2} \)
2. \( \sqrt{10} - \sqrt{3} \)
3. \( \sqrt{9} - \sqrt{4} \)
4. \( \sqrt{8} - \sqrt{5} \)
5. \( \sqrt{6} - \sqrt{7} \)
