What is Cube Root of 74

• Cube root of 74 is written as $\sqrt[3]{74}$ (Radical form).
• $\sqrt[3]{74}$ = $\sqrt[3]{4.1983 \times 4.1983 \times 4.1983}$ = 4.1983
• In the exponential form, the cube root of 74 is expressed as $(74)^\frac{1}{3}$.

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 = 74
• x = integer guess of its cube root.

Let's assume x as 4. Since 74 lies between 64 (cube of 4) and 125 (cube of 5). So, we will consider the closest cube number here, i.e. 4.

Using the above formula & numbers, let's calculate the cube root of 74
