_____________ is an equation that contains radicals or rational exponents.

Let's determine the equation which contains radicals or rational exponents.
When an equation has radicals or rational exponents, it has the form below:
[tex]\begin{gathered} \sqrt{2x+2}=\sqrt[3]{4x-6} \\ \\ OR \\ \\ (2x+3)^{\frac{1}{2}}=(2x-6)^{\frac{1}{3}} \end{gathered}[/tex]The expressions which make up the equation are called radical expressions while the equation is called an radical equation.
Therefore, an equation that contains radicals or rational exponents is a radical equation.
ANSWER:
Radical equation.
