To add, simplify, and state the domain of the expression (t^2s)/(rs) + (rs^2)/(rt), we first need to find a common denominator. The common denominator in this case is rst.

Next, we can rewrite the expression with the common denominator: (t^2s * t) / (rs * t) + (rs^2 * s) / (rt * s).

Simplifying further, we get (t^3s) / (rst^2) + (rs^3) / (rst^2).

To add these fractions, we combine the numerators over the common denominator: (t^3s + rs^3) / (rst^2).

Finally, we state the domain of the expression. The domain is the set of all real numbers that make the expression defined. In this case, the expression is defined for all values of t, r, and s except when the denominator becomes zero. Therefore, the domain is t ≠ 0, r ≠ 0, and s ≠ 0.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
