What will come in place of question mark (?) in the following questions ?
`sqrt(sqrt(4624) + sqrt(5776)) = ?`

Options

A. 144
B. 288
C. 12
D. 24

Answer

To solve the expression \( \sqrt{\sqrt{4624} + \sqrt{5776}} \), we will follow these steps:

### Step 1: Calculate \( \sqrt{4624} \)
First, we need to find the square root of 4624.

\[ \sqrt{4624} = 68 \]

### Step 2: Calculate \( \sqrt{5776} \)
Next, we calculate the square root of 5776.

\[ \sqrt{5776} = 76 \]

### Step 3: Add the results from Step 1 and Step 2
Now, we add the results from the previous two steps.

\[ 68 + 76 = 144 \]

### Step 4: Calculate the square root of the sum
Finally, we take the square root of the sum we calculated in Step 3.

\[ \sqrt{144} = 12 \]

### Conclusion
Thus, the value that comes in place of the question mark (?) is:

\[ \boxed{12} \]
