Explanation:
The square root of 22 is an irrational number, which means it cannot be expressed exactly as a finite decimal or a fraction. However, we can approximate it by finding the whole number that is closest to it.
To do this, we can use a calculator or estimation. For example, we can guess that the square root of 22 is between 4 and 5, since 4 squared is 16 and 5 squared is 25. Then we can try averaging these two numbers:
(4 + 5) / 2 = 4.5
This means that 4.5 is an approximate value of the square root of 22. The nearest whole number to 4.5 is 5, so we can say that the whole number nearest to the square root of 22 is 5.
