Conjugates are pairs of complex numbers or algebraic expressions that have the same real part but opposite signs for their imaginary parts. In algebra, conjugates are often used in rationalizing denominators or simplifying radical expressions.

Complex Numbers:

Numbers that consist of both real and imaginary parts, usually expressed in the form a + bi, where "a" represents the real part and "bi" represents the imaginary part.

Radical Expressions:

Expressions containing square roots or higher order roots (√x, ∛x) that cannot be simplified further without using radicals.
