In each question, what will come in place of question mark?
`14 cdot 14 xx 2 cdot 40 + 6 cdot 064 = ?`

Options

A. `33 cdot 396`
B. `40 cdot 000`
C. `34 cdot 064`
D. `34 cdot 000`

Answer

To solve the expression \( 14.14 \cdot 2.40 + 6.064 = ? \), we will follow the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)). Here, we only have multiplication and addition.

### Step-by-Step Solution:

1. **Multiply \( 14.14 \) by \( 2.40 \)**:
\[ 14.14 \cdot 2.40 = 33.936 \]

2. **Add \( 6.064 \) to the result from step 1**:
\[ 33.936 + 6.064 \]

To perform the addition, align the numbers:
```
33.936
+ 6.064
---------
```

Now, add column by column from right to left:
- **Thousandths place**: \( 6 + 6 = 12 \) (write down 2, carry over 1)
- **Hundredths place**: \( 3 + 0 + 1 = 4 \)
- **Tenths place**: \( 9 + 0 = 9 \)
- **Units place**: \( 3 + 6 = 9 \)
- **Tens place**: \( 0 + 0 = 0 \) (write down 0)
- **Hundreds place**: \( 3 + 0 = 3 \)

Thus, we have:
\[ 33.936 + 6.064 = 40.000 \]

3. **Final Result**:
\[ ? = 40.00 \]

### Conclusion:
The value that comes in place of the question mark is \( 40.00 \).
