Step-by-step explanation:

Answer 2

1221 is not a perfect square so square root is not possible.

Step-by-step explanation:

Let a number 1521, find the square root by using vedic maths.

step -1 Break into two parts 15 and 21.  

Consider nearest and smallest square for the first part which is 3 and consider the nearest square for the second part which has the same unit digit and which could be 1 or 9.

Hence, the square root of 1521 could be combination of three, one that will be (31) and the combination of three, nine that will be (39).

Step – 2 Multiply 3  with 1 and  9. Consider those value which are grater then the first part .  

Therefore,

$3\times 1 =3\\\\\, 3\times 9=27$

Now, 27>15  

Than the square root of 1521 is 39 .
