          SQUARES AND SQUARE ROOTS   Square number - The square of a number is the product of the number with the number itself.  A given number is a perfect square if its prime factors can be expressed in pairs of equal factors.  A perfect square number is never negative. For example - 8^2 = (8×8) = 64 Facts About Squares -  1. A number ending in 2, 3, 7 or 8 is never a perfect square.  2. A number ending in an odd number of zeros is never a perfect square.  3. The square of an even number is always even.  4. The square of an odd number is always odd.  5. The ending digits of a square number is 0, 1, 4, 5, 6, or 9 only.  Note:- It is not necessary that all numbers ending with digits 0, 1, 4, 5, 6, or 9 are square numbers.  Important Facts-  1. Numbers ending in an even number of zeros are not necessarily perfect squares. Eg- 3700, 290000, 47000000.   Practice Questions :-  1. Find the square of 54 ?  2. What least number must be added to 5607 to mak
