Use the formula
$$\ln(x)\approx x-{x↑2\over 2}+{x↑3\over 3}-{x↑4\over 4}+\cdots -{x↑{10}\over 10}$$
to estimate $\ln(y)$, taking $y$ from an input file. Try $y=1.2$.

If $a$ and $b$ are integers, and $c$ is a positive integer,
$(a+b\sqrt{2}\,)↑c$ can be simplified to $d+e\sqrt{2}$, where $d$ and~$e$
are integers. Write a program to read $a$, $b$, $c$ and print $d$,~$e$.
Try it on $(-1+\sqrt{2}\,)↑{10}$.
