Question

All square roots are irrational except

  1. Lovely squares
  2. Perfect squares
  3. Natural squares
  4. Neat squares

hintHint:

Squares as well as square roots both ideas are diametrically opposed to one another. Squares are the numbers that are produced when a value is multiplied by itself. In contrast, a number's square root is a value that, when multiplied by itself, returns the original value.
We have asked to fill in the blank: All square roots are irrational except ___________.

The correct answer is: Perfect squares


    As we discussed above Squares as well as square roots both ideas are diametrically opposed to one another.
    Let's take an example: 
    2 cross times 2 equals 2 squared equals 4
square root of 4 equals square root of 2 cross times 2 end root equals 2
    A number that may be written as the sum of two equal integers is referred to as a perfect square.
    So with this we can say that all square roots are irrational except Perfect Square. 

    Here we used the concept of squares and the square roots to understand and answer the question. An integer that can be expressed as the square of another integer is called a perfect square. In other words, it is defined as the product of some integer with itself. So the answer is perfect square.
