Explain the relationship between radical equations and complex numbers. what are the most important things to keep in mind when working with radical equations and complex numbers

Radical equations are equations that have at least one variable or number associated with a square root (example:  ). A complex number is any combination of a real number and an imaginary number (example: 2i)

It is often possible for complex numbers to be one or more of the solutions to a radical equation; For example, √-1 = i
