$16.02 \times 0.001 = ?$

If the numbers $\sqrt[3]{9}, \sqrt[4]{20}, \sqrt[6]{25}$ are arranged in ascending order,then the correct arrangement is:

$\frac{69842 \times 69842 - 30158 \times 30158}{69842 - 30158} = ?$

In a pair of fractions,fraction $A$ is twice the fraction $B$ and the product of the two fractions is $\frac{2}{25}.$ What is the value of fraction $A$?

If $x^{3}+3x^{2}+3x=7,$ then $x$ is equal to
