How do square roots work with exponents?
Roots are the opposite of an exponent and are finding the base with a given exponent. The index, or the number on the radical sign, tells how many times to multiply a number to get the radicand, the number on the inside of the radical sign.
What are the rules of exponents and radicals?
Definition: A radical represents a fractional exponent in which the numerator of the fractional exponent is the power of the base and the denominator of the fractional exponent is the index of the radical. Product: The nth root of a product is equal to the product of the nth root of each factor.
