Find the value of question mark(?) in the following questions ?
`36xx(12)^2-(18)^2`=?

Options

A. 12
B. 0.8
C. 0.6
D. None of these

Answer

To solve the expression \( 36 \times (12)^2 - (18)^2 \), we will follow these steps:

### Step 1: Calculate \( (12)^2 \)
First, we need to calculate \( 12^2 \):
\[ 12^2 = 144 \]

### Step 2: Substitute \( (12)^2 \) into the expression
Now we substitute \( 144 \) back into the expression:
\[ 36 \times 144 - (18)^2 \]

### Step 3: Calculate \( (18)^2 \)
Next, we calculate \( 18^2 \):
\[ 18^2 = 324 \]

### Step 4: Substitute \( (18)^2 \) into the expression
Now we substitute \( 324 \) back into the expression:
\[ 36 \times 144 - 324 \]

### Step 5: Calculate \( 36 \times 144 \)
Now we calculate \( 36 \times 144 \):
\[ 36 \times 144 = 5184 \]

### Step 6: Subtract \( 324 \) from \( 5184 \)
Finally, we subtract \( 324 \) from \( 5184 \):
\[ 5184 - 324 = 4860 \]

### Conclusion
Thus, the value of the question mark (?) is:
\[ \boxed{4860} \]
