Things You Need to Know
- Radicals are numbers that have a root sign on them.
- Entire radicals are where there are no numbers outside the root sign.
- Mixed radicals are where there is a coefficient multiplying the rest of the radical.
- The index is the type of root (index of 2 is a square root, index of 3 is a cube root, etc.).
- The radicand is the number under the root sign.
- Radicals can only be added or subtracted if they have the same radicand.
- Radicals can be multiplied by multiplying the coefficients together, and the radicands together.
- Radicals can also be divided in the same manner.
- We don't like expressions with a radical as a denominator. We can get rid of this by "rationalizing the denominator", which means to multiply both the top and bottom by the denominator's radical.
