e = \sqrt[3]96 = \sqrt[3]8 \cdot 12 = 2\sqrt[3]12 - Sourci

Let’s begin by examining the cube root of 96:
∛96

Our goal is to factor 96 into components that include perfect cubes, since cube roots of perfect cubes simplify neatly. Notably, 96 can be factored as:
96 = 8 × 12
And since 8 is a perfect cube (because 2³ = 8), we can rewrite the cube root using this factorization.

One of the essential rules for cube roots is the property:
∛(a × b) = ∛a × ∛b

Using this, we apply it to ∛96:
∛96 = ∛(8 × 12) = ∛8 × ∛12

Because ∛8 = 2, this becomes:
∛96 = 2 × ∛12 = 2∛12

Expressing ∛96 as 2∛12 offers practical advantages:

• Simpler Calculations: Working with cube roots of integers is often more intuitive when simplified. Since 12 is not a perfect cube, leaving it as ∛12 preserves accuracy without unnecessary approximation.
  
• Clearer Numeric Meaning: The factor 2 provides a numerical multiplier that highlights the root’s scale, making it easier to compare values or perform estimations.
  
• Foundation for Further Algebra: This form is especially useful in equations, integrals, and expressions involving cube roots, enabling smoother manipulation and simplification.

Mastering cube root simplifications — like recognizing ∛96 = 2∛12 — strengthens algebraic fluency and efficiency. Whether solving textbook problems or tackling real-life challenges, the ability to rewrite ∛(a × b) using factorization empowers clearer thinking and more accurate calculations.

In summary:
∛96 = ∛(8 × 12) = ∛8 × ∛12 = 2∛12**
This elegant identity transforms a seemingly complex root into a powerful and accessible form — a cornerstone in mastering cube roots.
