WebRadical Equations Definition. A radical equation is an equation in which a variable is in the radicand of the expression. At least one radical sign of a radical equation includes a variable. In other words, a radical equation has a variable with a rational exponent. Examples of Radical Equations: $\sqrt{a} + 4 = 13,\; \sqrt{x\;-\;1} = 5$ WebA radical expression, also referred to as an n th root, or simply radical, is an expression that involves a root. Radicals are expressed using a radicand (similar to a dividend ), a radical symbol, and an index, which is typically denoted as "n." The most common radicals we see are the square root and the cubed root.
