Answer:

√16

General Formulas and Concepts:

Math

  • Rational Numbers - numbers that can be defined as a single integer or terminating decimal
  • Irrational Numbers - numbers that do not have a terminating decimal; numbers that infinitely go on

Explanation:

√2 is incorrect because when we evaluate the square root, we will get a never-ending decimal: 1.4142135623731...

3.44444444... is incorrect because it is a never-ending decimal (the bar above 4 signifies this).

√10 is incorrect because when we evaluate the square root, we will get a never-ending decimal: 3.1622776601684...

√16 is correct because when we evaluate the square root, we get a ending decimal/a whole integer: 4

Therefore √16 is the correct answer.
