You can create a function to relate
the value of x raised to power y.
One clever way to exponentiate
is to repeat a simple multiply.

If y is zero, just return a one–
for ev’ry number, that will be the case.
And when y equals one, your work is done–
the answer will be x, your starting base.

For ev’ry other value y can be,
just multiply by x, recursively.
