Respuesta :
the rational exponent expression of sixth root of f is f to the one sixth power
proof
A^1/n, is called n-th root of A, for all n differ from zero

The answer is option B "[tex] f^\frac{1}{6} [/tex]." Rational exponents are exponents that are integers and are fractions. Remember that rational numbers are numbers that can be changed into a fraction but it's the same way with rational exponents they are integers (negative or positive) that can be rewritten as fractions.
Hope this helps!
