Terms | Definitions |
|---|---|
 radicand | the number inside the radical sign √ ← under the line. |
| vinculum | a horizontal line placed over a mathematical expression, used to indicate that it is to be considered a group |
| index | the number over the radical sign √ indicating the root of the radicand. |
| root | a number indicating the number of repetitive factors needed to obtain the radicand, ie. square root (xx) cube root (xxx). |
| radical | the check mark part of the radical expression, √ . |
| roots vs radicals | these terms are opposites and are used to solve equations or inequalities containing them. The square root of 9 is the opposite of 3 squared or (-3) squared. |
| the sum of radical expressions can be obtained | if and only if the radicands are the same. |
| The product of a radical expressions can be obtained by | multiplying the radicands of each radical expression. √(8) times √(2) =√(8)(2) = √16 = 4 |
| simplifying radicals (square roots only) | 1. divide the number inside the radical into two factors, one of which is a perfect square 2. square root the perfect square 3. leave the non-perfect square under the radical |
| How can radical expressions be written without a radical sign? | Change the root to a fraction with the root as the denominator and any exponents on a radicand as the numerator. |
