Answer 2

Answer:Square root of 49 is 7, 25 is 5 and 64 is 8

Step-by-step explanation: Now,

49-1 = 48, 48-3 = 45, 45-5 = 40, 40-7= 33, 33 - 9 = 24 - 11 = 13 - 13 = 0. Square root of 49 is 7.

25 - 1 = 24, 24 -3 = 21, 21- 5 = 16, 16 - 7 = 9 - 9 =0. Sqaure root of 25 is 5.

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

Square root of 64 is 8.
