How to write square and square roots simple methods are shown here. Friends any Number we multiply by its self then the new value becomes a square of that Number.
Ex. Squares
(1)2 = 1 x 1 = 1 (2)2 = 2 x 2 = 4 (3)2 = 3 x 3 = 9
(4)2 = 4 x 4 = 16 (5)2 = 5 x 5 = 25 (6)2 = 6 x6 = 36
(7)2 = 7 x 7= 49 (8)2 = 8 x 8= 64 (9)2 = 9 x 9= 81
(10)2 = 10 x 10=100 (11)2 = 11 x 11 = 121 (12)2 = 12 x12 = 144
(13)2 = 13 x 13= 169 (14)2 = 14 x 14 =196 (15)2 = 15 x 15= 225
(16)2 = 16 x 16 =256 (17)2 = 17 x 17 =289 (18)2 = 18 x18 = 324
(19)2 = 19 x 19 =361 (20)2 = 20 x20 = 400 (21)2 = 21 x 21 =441
(22)2 = 22 x 22 =484 (23)2 = 23 x23 = 529 (24)2 = 24 x 24 576
(25)2 = 25 x 25 = 625 (26)2 = 26 x 26 = 676 (27)2 = 27 x 27 = 729
(28)2 = 28 x 28 = 784 (29)2 = 29 x 29 = 841 (30)2 = 30 x 30 = 900
(31)2 = 31 x 31= 961 (32)2 = 2 x 32 = 1024 (33)2 = 33 x33 = 1089
(34)2 = 34 x 34 = 1156 (35)2 = 35 x 35 = 1225 (36)2 = 36 x 36 = 1296
(37)2 = 37 x 37 = 1369 (38)2 = 38 x 38 = 1444 (39)2 = 9 x 39 = 1521
(40)2 = 40 x 40 = 1600 (41)2 = 41 x 41 = 1681 (42)2 = 42 x 42 = 1764
(43)2 = 43 x 43= 1849 (44)2 = 44 x 44 = 1936 (45)2 = 45 x 45 = 2025
(46)2 = 46x 46 = 2116 (47)2 = 47 x 47 = 2209 (48)2 = 48 x 48 = 2304
(49)2 = 49 x 49 = 2401 (50)2 = 50 x 50 = 2500
Some Tricks to Simply get Square
- 15 x 15
Here
5 x 5 = 25
And another number
1 and after that number is 2 so,
Multiply these two numbers.
Write two value 2 25 = 225
The square of 15 is 225
2) 45
Here
5 x 5 = 25
And another number is
4 and after that number is 5 so,
Multiply these two numbers
Write two values : 20 25 = 2025
The square of 45 is 2025
Conclusion: This is the simplest method to find any numbers square and square roots.
