What is Cube Root of 12

• Cube root of 12 is written as $\sqrt[3]{12}$ (Radical form).
• $\sqrt[3]{12}$ = $\sqrt[3]{2.2894 \times 2.2894 \times 2.2894}$ = 2.2894
• In the exponential form, the cube root of 12 is expressed as $(12)^\frac{1}{3}$.

Cube Root by Halley's Method

Halley's method is an iterative technique used to find cube roots. To find the cube root of a number using Halley's method, follow these steps:

Its formula is $\sqrt[3]{a} ≈ x \left( \frac{ \left( x^3 + 2 \times a \right) }{ \left( 2 \times x^3 + a \right) } \right)$ where,

• a = number whose cube root is being calculated = 12
• x = integer guess of its cube root.

Let's assume x as 2. Since 12 lies between 8 (cube of 2) and 27 (cube of 3). So, we will consider the closest cube number here, i.e. 2.

Using the above formula & numbers, let's calculate the cube root of 12
