Explanation:
A radical expression is an algebraic expression that includes a radical, so we can write a radical expression in the following form;
[tex]\sqrt[n]{a} \\ \\ \\ Where: \\ \\ a:Radicand \\ \\ n:Index \\ \\ \sqrt{}:Radical \ sign[/tex]
On the other hand, a rational expression is an expression formed by the ratio of two polynomials, in other words we can write:
[tex]\frac{P(x)}{Q(x)} \\ \\ \\ Where: \\ \\ P(x) \ and \ Q(x) \ are \ polynomials[/tex]
For instance, this is a rational expression:
[tex]\frac{3x^3+4x^2+5x+2}{x^2-4}[/tex]
