Standard Operating Procedure for Evaluating Radical Expressions

You are assisting in the creation of a training manual for new quality control technicians. One section of the manual must define the rules for evaluating radical expressions with negative values under the root (negative radicands). Write a brief entry for the manual that states the general rule for determining if an expression like an\sqrt[n]{a} (where aa is negative) results in a real number. Your response should clearly distinguish between cases where the index nn is even versus when it is odd.
