For example, the cube root of -8 is -2, since (-2) 3 = (-2) (-2) (-2) = -8 (a negative raised …
WebSince the square root of a negative number is not a real number, we cannot use the Product Property for Radicals. In order to multiply square roots of negative numbers we should first write them as complex numbers, using − b = b i. This is one place students tend to make errors, so be careful when you see multiplying with a negative square root. WebSo the answer, this part right over here, is just going to simplify to 8. And so our answer to this, the cube root of negative 512, is negative 8. And we are done. And you could verify this. Multiply negative 8 times itself three times. Well, let's just do it.
