How are exponents and radicals used to represent roots of real numbers?

A radical is used to represent the square root of a number. For example, ...

represents the square root of 2, a value that, when multiplied by itself, gives 2.

A radical with an index (n) is used to represent the n-th root of a number. For example, ...

represents the 5th root of 3. The product of this number with itself a total of 5 times gives 3.

Either of these roots can be represented using fractional exponents:

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p

35/2 is it i think maybe
