Radical Expressions and Equations

Radical equations and expressions are mathematical components that incorporate roots, encompassing square roots, cube roots, and the likes. These expressions are characterized by the presence of a number or variable that is placed beneath a root symbol. On the other hand, these expressions become equations when they are equated with different values. The resolution of these equations frequently necessitates the segregation of the radical, followed by squaring the components on either side.
