a3 - b3 = (a - b) (a2 + a b + b2) (20)
(a + b)3 = a3 + 3 a2 b + 3 a b2 + b3 (21)
(a - b)3 = a3 - 3 a2 b + 3 a b2 - b3 (22)
a1/2 a1/2 = a (23)
a1/3 a1/3 a1/3 = a (24)
(a1/3)3 = a (25)
(a2)1/3 = (a1/3)2 = a2∕3 (26)
(a1/3)1/4 = a1/3 1/4 = (a1/4)1/3 (27)
(a b)1/3 = a1/3 b1/3 (28)
(a / b)1/3 = a1/3 / b1/3 (29)
(1 / a)1/3 = 1 / a1/3 = a-1/3 (30)
a1/2 = √a
