To find:

Which of the following a perfect square

Solution:

A perfect square

• A perfect square or square number is a positive integer that is square of an another integer or which can be written in the form of a²
• Example:

    here are first 10 natural numbers squares

    Square of 2 = 2 × 2 = 4, here 4 can be written as 2²  

    Square of 3 = 3 × 3 = 9, here 9 can be written as 3²  

    Square of 4 = 4 × 4 = 16, here 16 can be written as 4²  

    Square of 5 = 5 × 5 = 25, here 25 can be written as 5²  

    Square of 6 = 6 × 6 = 36, here 36 can be written as 6²  

    Square of 7 = 7 × 7 = 49, here 49 can be written as 7²  

    Square of 8 = 8 × 8 = 64, here 64 can be written as 8²  

    Square of 9 = 9 × 9 = 81, here 81 can be written as 9²  

    Square of 10 = 10× 10 = 100, here 100 can be written as 100²  

From above example we can conclude that when we square a number the unit digit must be 1 or 4 or 5 or 6 or 9 or 0
