$\frac{(272-32)(124+176)}{17 \times 15-15} = ?$

What approximate value will come in the place of the question mark $(?)$ in the following equation? (You are not expected to calculate the exact value.)
$7441 \div 34 \times 12 = ? \times 9 + 110$

If the sum of squares of two real numbers is $41$ and their sum is $9,$ then the sum of cubes of these two numbers is

The value of $\frac{1}{2+\frac{1}{2+\frac{1}{2-\frac{1}{2}}}}$ is

The value of $\frac{1}{2} + \frac{1}{2 \cdot 3} + \frac{1}{2 \cdot 3 \cdot 4} + \frac{1}{2 \cdot 3 \cdot 4 \cdot 5}$ is correct to three places of decimal:

$\frac{\frac{64}{121}-\frac{9}{64}}{\frac{8}{11}+\frac{3}{8}} = ?$
