Is (√(x+2))/(x^(2)+4) a rational expression?

Question

I have to write a five paragraph paper on this.  Why or why not is this rational? Why is it easy to miss this?

Answer 1

An expression that is ratio between two polynomials is called rational expression.

A polynomial doesn't have squre root.a polynomial coefficients powers have only with integers.

Given expression  is having squre root and the variablex is underthe radical.

it is not a rational expression.
