Our form of representing polynomials using the index for the exponent is not so good for a polynomial like \(4 x^{512} + 7 x^{256} + 1\) We could also represent polynomials by a list of lists. e.g. .. sourcecode:: python
[[4,512],[7,256],[1,0]]
Here each term is a two element list of [coefficient, exponent]
Rewrite polynomials.py so that it uses this new representation of a polynomial.
