Question

Which of the following is the rational exponent expression of sixth root of f?

Answer 1

The answer is option B "$f^\frac{1}{6}$." 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!

Answer 2

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
