WebCube Root of 4 by Halley's Method Its formula is ∛a ≈ x ( (x 3 + 2a)/ (2x 3 + a)) where, a = number whose cube root is being calculated x = integer guess of its cube root. Here a = 4 Let us assume x as 1 [∵ 1 3 = 1 and 1 is the nearest perfect cube that is less than 4] ⇒ x = 1 Therefore, ∛4 = 1 (1 3 + 2 × 4)/ (2 × 1 3 + 4)) = 1.5 ⇒ ∛4 ≈ 1.5 WebCube Root of 20 by Halley's Method Its formula is ∛a ≈ x ( (x 3 + 2a)/ (2x 3 + a)) where, a = number whose cube root is being calculated x = integer guess of its cube root. Here a = 20 Let us assume x as 2 [∵ 2 3 = 8 and 8 is the nearest perfect cube that is less than 20] ⇒ x = 2 Therefore, ∛20 = 2 (2 3 + 2 × 20)/ (2 × 2 3 + 20)) = 2.67
