SURDS
Surds are irrational numbers expressed as roots, such as √2 or √3, that cannot be simplified to a whole number. They are often left in root form for precision. Surds follow specific rules for simplification, multiplication, and division, such as √a × √b = √(a×b) and √a / √b = √(a/b). Rationalizing surds involves eliminating roots from the denominator, like multiplying √2/√3 by √3/√3 to get (√6)/3. Surds are commonly used in geometry and algebra for exact calculations.
