Key Terms
- index
- n is called the index of the radical.
- like radicals
- Radicals with the same index and same radicand are called like radicals.
- like square roots
- Square roots with the same radicand are called like square roots.
- nth root of a number
- If , then is an nth root of .
- principal nth root
- The principal nth root of is written .
- radical equation
- An equation in which the variable is in the radicand of a square root is called a radical equation
- rational exponents
- If is a real number and , .
