Roots
Square Root: The square root of a number n is a value that, when multiplied by itself, equals n.
√n = n^(1/2)
Cube Root: The cube root of n is a value that, when cubed, equals n.
∛n = n^(1/3)
Perfect Square: A number is a perfect square if its square root is a whole number.
Examples:
- √4 = 2 (perfect square)
- √9 = 3 (perfect square)
- √2 = 1.4142… (not a perfect square)
- ∛27 = 3 (perfect cube)
- ∛8 = 2 (perfect cube)
Square roots of negative numbers are not real numbers — they are imaginary (e.g., √-1 = i).
