then u have to study multilpication.

u can understand that

1²=1(odd number is 1)

2² =4(4)

3² =9(9)

4² =(16(6)

5²= 25(5)

6²= 36(6)

7²=49(9)

8²=64(4)

9²=81(1)

10²=100(0)

now u can find roots easily,

eg. √1681=

In this number (1) is the place of odd number. we know that it will be a number that's odd number is 1 or 9

4*4=16

so we can easily calcuculate 40*40=1600

1681 is near the number 1600

so 1681's root is 41
