Show how to extend the basic differentiator to handle more kinds of expressions. For instance, implement the differentiation rule
![2.56](https://sicp.hexlet.io/build/assets/2_56-BKOxnC9z.gif)
by adding a new clause to the
deriv
program and defining appropriate procedures
exponentiation?
,
base
,
exponent
, and
make-exponentiation
. (You may use the symbol
**
to denote exponentiation.) Build in the rules that anything raised to the power
0
is
1
and anything raised to the power
1
is the thing itself.
