Find the value of question mark(?) in the following questions ?
`sqrt(1024) xx sqrt?=768`

Options

A. 28
B. 576
C. 676
D. 24

Answer

To solve the equation \( \sqrt{1024} \times \sqrt{?} = 768 \), we will follow these steps:

### Step 1: Simplify \( \sqrt{1024} \)
First, we need to find the value of \( \sqrt{1024} \).

\[ \sqrt{1024} = 32 \]

### Step 2: Substitute into the equation
Now, we can substitute \( \sqrt{1024} \) back into the equation:

\[ 32 \times \sqrt{?} = 768 \]

### Step 3: Isolate \( \sqrt{?} \)
Next, we will isolate \( \sqrt{?} \) by dividing both sides of the equation by 32:

\[ \sqrt{?} = \frac{768}{32} \]

### Step 4: Calculate \( \frac{768}{32} \)
Now, we perform the division:

\[ \frac{768}{32} = 24 \]

### Step 5: Square both sides
To find the value of \( ? \), we square both sides of the equation:

\[ ? = 24^2 \]

### Step 6: Calculate \( 24^2 \)
Finally, we calculate \( 24^2 \):

\[ 24^2 = 576 \]

Thus, the value of the question mark \( ? \) is:

\[ ? = 576 \]

### Final Answer:
The value of the question mark is \( 576 \).
