1. Simplify `(a^2b^0c)^0`

Anything to raised to the zero is equal to one, so the answer here is 1.

2. Simplify `x^{-2}y^3`

We can write `x^{-2}` as `\frac{1}{x^2}` ,so this simplifies to `\frac{y^3}{x^2}`

3. Simplify `3x^{-2}`

Same strategry as in #2, this simplifies to `3/x^2`

4. Simplify `n^2 / n^(-3)`

Here we use the rule `x^a / x^b = x^(a-b)` , giving us the simplified result `n^5`
