🔢 What is a Cube Root?

The cube root of a number is the value that, when multiplied by itself three times, gives the original number.
For example:
∛27 = 3, because 3 × 3 × 3 = 27
The cube root is represented as ∛ or as an exponent of 1/3. Cube roots are commonly used in geometry, algebra, physics, and real-world applications such as calculating volume and solving for unknown values in formulas.
Unlike square roots, cube roots work with both positive and negative numbers, since multiplying a negative number three times also results in a negative value.

✍️ Example Calculation:

∛64 = 4, because 4 × 4 × 4 = 64
∛−125 = −5, because −5 × −5 × −5 = −125
∛0.008 = 0.2, because 0.2 × 0.2 × 0.2 = 0.008
