Simplify the following:
(a+10)(a+10)

## Answers (1) 2021-02-20
$$\displaystyle{\left({a}+{10}\right)}{\left({a}+{10}\right)}={a}^{{2}}+{2}{a}{\left({10}\right)}+{10}^{{2}}$$
$$\displaystyle={a}^{{2}}+{20}{a}+{100}$$

The rational numbers are dense in $$\displaystyle\mathbb{R}$$. This means that between any two real numbers a and b with a < b, there exists a rational number q such that a < q < b. Using this fact, establish that the irrational numbers are dense in $$\displaystyle\mathbb{R}$$ as well.
