Question

Find the square root 1024 by using ‘Viiokanam’ method.

Answer 1

1024

(i) Making pairs from right to left, first pair = 24

(ii) Extreme digit of first pair = 4

∴ Extreme digit in possible square root may be either 2 or 8.

(iii) Greatest square root within the maximum limit 10 = 3.

∴ Possible square root may be either 32 or 38.

Product of 3 and 8 = 3 x 8 = 24

(iv) ∵ 10 < 24

∴ Smallest number will be square root.

Hence square root = 32
