Cube Root

The cube root of a number is a value that, when multiplied by itself three times, gives the original number. It is denoted by the symbol ∛𝑥 , where 𝑥 is the number you’re finding the cube root of.

Key Concepts of Cube Roots:

1. Definition:
   For a number 𝑥, the cube root ∛𝑥 is the number 𝑦 such that 𝑦³ = 𝑥.
2. Properties of Cube Roots:
   

• Cube roots of negative numbers are negative.
• Cube roots work similarly for fractions.
