Gw mau tau 1) 27-1 = 26 dari Akar kuadrat. Jelasin dalam bahasa sunda

5) 11-9 = 2  First number is 5

2 x 100 = 200 and 5 x 20 + 1 = 101

1) 200-101 = 99 Next number is 1

99 x 100 = 9900 and 51 x 20 + 1 = 1021

9) 1676-1037 = 639 Next number is 9

The result gives us 5.19 as the square root of 27

Quadratic irrationals, that is numbers involving square roots in the form (a+√b)/c, have periodic continued fractions. This makes them éasy to calculate recursively given the period. For example, to calculate √2, we maké use of the fact that √2-1 = [0;2,2,2,2,2,...], and use the recurrence relation
