What will come in place of the question mark (?) in the given questions ?
`34xx80+?^2=7500-4251`

Options

A. 17
B. 21
C. 33
D. 23

Answer

To solve the equation \( 34 \times 80 + ?^2 = 7500 - 4251 \), we will follow these steps:

1. **Calculate \( 34 \times 80 \)**:
\[ 34 \times 80 = 2720 \]

2. **Calculate \( 7500 - 4251 \)**:
\[ 7500 - 4251 = 3249 \]

3. **Set up the equation**:
Now we can rewrite the equation as:
\[ 2720 + ?^2 = 3249 \]

4. **Isolate \( ?^2 \)**:
To find \( ?^2 \), we subtract 2720 from both sides:
\[ ?^2 = 3249 - 2720 \]
\[ ?^2 = 529 \]

5. **Find the value of \( ? \)**:
To find \( ? \), we take the square root of both sides:
\[ ? = \sqrt{529} = 23 \]

Thus, the value that comes in place of the question mark (?) is **23**.
