![]() ![]() In ∛x, the radicand is x since it is the quantity inside the radical sign. ![]() It is the one that you are taking the root of. On the other hand, the radicand is the quantity inside the radical sign. This means that we are taking the cube root of the number inside the radical sign. In this case, we are seeing the radical symbol with a 3 written on the left side. The radical symbol or radical sign is the symbol that indicates we are taking the root of a number. We can extend the concept of square roots and cube roots to the fourth root (∜), fifth root, sixth root, and so on. For instance, ∛27 = 3 since 3 x 3 x 3 = 27. The cube root of the number is the number that when you multiplied to itself thrice (or three times) will produce the original number. However, radicals are not just square roots. You know that the square root of a number is the number that when multiplied by itself will produce the original number. The first time you probably encountered radicals is when you first learned about the square root of numbers. 2. Answer Key What Is a Radical?Ī radical is an expression or quantity that has the radical symbol or uses a root (√).

This time, we are going to explore the realm of quantities with exponents that are rational numbers. In the previous chapters, you encountered quantities with exponents that are integers (i.e., 0, positive whole numbers, and negative whole numbers). ![]()
