Question 33782: Hello. The problem is -3 (cube root, I dont know how to type the sign) -27. I have come up with -3 as a solution. The instructions say evaluate the radical expression if it is a real number. Approximate irrational numbers to the nearest hundredth. If not a real number than state so. Can you possibly tell me if I have the correct answer? Any help would be appreciated. Thanks in advance.
