What value should come in place of question mark (?)
`(1.06+0.04)^2-?=4xx1.06xx0.04`

Options

A. 1.0404
B. 1.4
C. 1.5
D. 1.45

Answer

To solve the equation \( (1.06 + 0.04)^2 - ? = 4 \times 1.06 \times 0.04 \), we will follow these steps:

### Step 1: Simplify the left side
First, we need to calculate \( (1.06 + 0.04)^2 \).

\[ 1.06 + 0.04 = 1.1 \]
Now, we square \( 1.1 \):

\[ (1.1)^2 = 1.1 \times 1.1 = 1.21 \]

### Step 2: Calculate the right side
Next, we calculate \( 4 \times 1.06 \times 0.04 \).

\[ 1.06 \times 0.04 = 0.0424 \]
Now, multiply by 4:

\[ 4 \times 0.0424 = 0.1696 \]

### Step 3: Set up the equation
Now we have:

\[ 1.21 - ? = 0.1696 \]

### Step 4: Solve for ?
To find \( ? \), we rearrange the equation:

\[ ? = 1.21 - 0.1696 \]

Now, we perform the subtraction:

\[ 1.21 - 0.1696 = 1.0404 \]

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

\[ ? = 1.0404 \]

### Final Answer
The correct answer is \( 1.0404 \).
