Additional comment

For positive numbers, square and square root are operations that preserve order. That is, the square of a larger number is larger than the square of a smaller number. Likewise, the square root of a larger number is larger than the square root of a smaller number. Here, ...

81 > 64 > 44 ⇔ √81 > √64 > √44.

If a number is not a perfect square (a number multiplied by itself), then its square root is irrational.
