Along a yard $225 \ m$ long,$26$ trees are planted at equal distances,with one tree at each end of the yard. What is the distance between two consecutive trees in meters?

What approximate value will come in the place of the question mark $(?)$ in the following question? (You are not expected to calculate the exact value.)
$(32.13)^{2} + (23.96)^{2} - (17.11)^{2} = ?$

$(0.1 \times 0.01 \times 0.001 \times 10^{7})$ is equal to

$3 \frac{1}{4} + 2 \frac{1}{2} - 1 \frac{5}{6} = \frac{(?)^{2}}{10} + 1 \frac{5}{12}$

$\sqrt[3]{-2197} \times \sqrt[3]{-125} + \sqrt[3]{\frac{27}{512}}$

What will come in the place of the question mark $(?)$ in the following equation?
$3463 \times 295 - 18611 = ? + 5883$
