Question

find the square root of 64 by subtraction method

Answer 1

Subtraction method :-

For finding the root of x, we subtract x with prime numbers until it comes to be zero.

So
64 - 1 = 63
63 - 3 = 60
60 - 5 = 55
55 - 7 = 48
48 - 9 = 39
39 - 11 = 28
28 - 13 = 15
15 - 15 = 0

Now we see the result is 0 We
Now we have to count how many times we subtract. We subtracted 8 times. So the square root is 8.


8 is your answer.


Hope it helps dear friend ☺️✌️
