Answer:
FACT ABOUT SQUARE NUMBER ARE
Step-by-step explanation:
1) 0, 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 12, ... are Square Numbers
2) Square numbers increase by 1, 3, 5, 7, ...
3) Square of ODD number is ODD; Square of EVEN number is EVEN
4) Squares end only in 1, 4, 6, 9 and 00, 25
5) Nos. ending in 2, 3, 7, 8, 0 (not 00), 5 (not 25) are not squares
6) Nos. ending in 1, 4, 6, 9, 00, 25 may or may not be squares
7) Squares of consecutive numbers differ by Sum of numbers
e.g. 262 - 252 = 25 + 26 = 51 or
If 252 = 625, 262 = 625 +(25 + 26) = 676
8) Group the digits of a square 2 by 2 from right (the last group on the left may be 2 or 1 digit) For every group, the square-root will have one digit.
9) If a perfect square ends in 1, its root will end in 1 or 9
4, 2 or 8
6, 4 or 6
9, 3 or 7
