# How do you write all the names that apply to sqrt36?

Jan 12, 2017

Natural, Integer, Rational, Real, Complex

#### Explanation:

Since $\sqrt{36} = 6 \left(\ge 0\right)$
it follows (by definition) that $\sqrt{36}$ is a Natural number.

And since $\mathbb{N} \left(\text{Natural") sub ZZ ("integer") sub QQ("Rational") sub RR("Real") sub CC ("Complex}\right)$

$\sqrt{36}$ is a member of all basic numeric types.

[I hope this is what you were after when you asked for the "names".]
