Question

√16 isAnd then it asks if it is undefined, irrational, and rational.

Answer 1

Rational numbers are the numbers that can be put in the form of the fraction

Ex:

`2,\text{ }(3)/(4)\text{ , }\sqrt[]{25},\text{ }(22)/(7),\text{ 100, }\ldots`

Irrational numbers are the numbers cannot be put in the form of the fraction

Ex:

`\sqrt[]{7},\text{ }\sqrt[3]{24},\pi,\ldots\ldots`

Let us check the question

`\sqrt[]{16}=\sqrt[]{(4)(4)}=4`

4 can be written in the form of the fraction, so it is a rational number
