Square root - practice problems

Roots in math refer to values that satisfy an equation when set to zero (e.g., x = 2 is a root of x² - 4 = 0 ).

The square root (√) of a number a is a value x such that x² = a (e.g., √25 = 5 ).

Higher-order roots, like cube roots (cbrt or ∛), solve equations such as x³ = 8 (result: x = 2 ).

Roots are fundamental in algebra, calculus, and real-world applications like physics (e.g., calculating distances or growth rates).
