Question

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

Answer 1

Natural, Integer, Rational, Real, Complex

Explanation:

Since `sqrt(36)=6 (>=0)`
it follows (by definition) that `sqrt(36)` is a Natural number.

And since `NN ("Natural") sub ZZ ("integer") sub QQ("Rational") sub RR("Real") sub CC ("Complex")`

`sqrt(36)` is a member of all basic numeric types.
