Rationals and Radicals

Description

The nth root is a number which, when multiplied by itself n times, equals a given number. nth roots can be expressed using a radical symbol or a rational exponent. The nth root of a is written as n√(a) or as a(1/n). It includes an example where the cube root of 125 equals 5 and the fourth root of 74 equals 7. This term introduces the concept of roots, laying a foundation for understanding radicals and their properties in rational and radical expressions.
