In cube root problems, it is possible to multiply a negative value times itself three times and get a negative answer. Difficulties, however, develop when we look at a problem such as . This square root problem is asking for a number multiplied times itself that will give a product (answer) of -16. There simply is no way to multiply a number times itself and get a negative result. Consider: (4) â¢ (4) = 16 and (-4) â¢ (-4) = 16.
