Roots and radical exponents are related concepts in mathematics. A root is a symbol that represents finding a number that, when multiplied by itself a certain number of times, gives the original number. For example, the square root of 9 is 3, because 3 x 3 = 9.

Radical exponents are a way of writing roots using exponents. They use the fractional exponent form to represent roots.

For example:

The square root of a number can be written as a fractional exponent with the numerator of 1 and the denominator of 2. So, the square root of 9 can be written as 9^(1/2) = 3. The cube root of a number can be written as a fractional exponent with the numerator of 1 and the denominator of 3. So, the cube root of 27 can be written as 27^(1/3) = 3. This is a more compact way of writing roots and can make some calculations easier to perform.
