What will come in place of question mark(?) in the following questions?
`98 ÷ 14 xx 49 - 294 = (?)^2`

Options

A. -14
B. `sqrt7`
C. -7
D. 196

Answer

To solve the equation \( 98 ÷ 14 \times 49 - 294 = (?)^2 \), we will follow these steps:

### Step 1: Perform the division
First, we will divide \( 98 \) by \( 14 \).

\[ 98 ÷ 14 = 7 \]

### Step 2: Multiply the result by \( 49 \)
Next, we will multiply the result from Step 1 by \( 49 \).

\[ 7 \times 49 = 343 \]

### Step 3: Subtract \( 294 \) from the result
Now, we will subtract \( 294 \) from the result obtained in Step 2.

\[ 343 - 294 = 49 \]

### Step 4: Set the equation to find \( (?)^2 \)
Now we have:

\[ (?)^2 = 49 \]

### Step 5: Solve for \( ? \)
To find \( ? \), we take the square root of \( 49 \).

\[ ? = \sqrt{49} = 7 \quad \text{or} \quad ? = -\sqrt{49} = -7 \]

Thus, the value of \( ? \) is \( 7 \) or \( -7 \).

### Final Answer
The value that comes in place of the question mark (?) is \( 7 \) (or \( -7 \)).
