1. The problem statement, all variables and given/known data

I need to find some huge numbers and don't know how to do it using a computer. Everything that I have tried doesn't work because the numbers are too big.

2. Relevant equations

The equations are 1/((1-x)(1-x^2)(1-x^3)) and 1/((1-x)(1-x^3)(1-x^4)) where x=10^30.

3. The attempt at a solution

$$\frac{-1}{x^6}$$ and $$\frac{-1}{x^8}$$. Those numbers you can easily compute exactly by hand =] I also assure you that neglecting the 1's creates a very small error indeed. We could carry out an analysis to find the maximum error made, but I can't be bothered, I'm sure you see its tiny as well.
