Question

Find the square root method repeated substraction A.144 B.64 C 121 d.49

Answer 1

Answer:

12, 8, 11, 7

Step-by-step explanation:

Square Root by Repeated subtraction method is

144 - 1 = 143......(1)

143 - 3 = 140......(2)

140 - 5 = 135.......(3)

135 - 7 = 128.........( 4)

128 - 9 = 119......... ( 5)

119 - 11 = 108..........( 6)

108 - 13 = 95.........( 7)

95 - 15 = 80.........(8)

80 - 17 = 63..........( 9 )

63 - 19 = 44.......( 10)

44 - 21 = 23......(11)

23  - 23 = 0............( 12)

hence the square root of the 144 is 12.

Similarly, you can calculate the square root of √64 = 8, √121 = 11, √49 = 7.
