Options

A. 26
B. 24
C. 28
D. 27

Explanation

To solve the expression \( ? = \sqrt{18 \times 32 + 11 \times 5 + 9 \times 5} \), we will follow these steps:

### Step 1: Calculate each multiplication
First, we will calculate the products in the expression.

1. Calculate \( 18 \times 32 \):
\[ 18 \times 32 = 576 \]

2. Calculate \( 11 \times 5 \):
\[ 11 \times 5 = 55 \]

3. Calculate \( 9 \times 5 \):
\[ 9 \times 5 = 45 \]

### Step 2: Add the results together
Now, we will add the results of the multiplications together:
\[ 576 + 55 + 45 \]

Calculating this step-by-step:
- First, add \( 576 + 55 \):
\[ 576 + 55 = 631 \]
- Next, add \( 631 + 45 \):
\[ 631 + 45 = 676 \]

### Step 3: Take the square root
Now that we have the total, we will take the square root of \( 676 \):
\[ ? = \sqrt{676} \]

### Step 4: Simplify the square root
The square root of \( 676 \) is:
\[ \sqrt{676} = 26 \]

### Final Answer
Thus, the final answer is:
\[ ? = 26 \]
