Answer 2

Explanation:

Given the problem is (the seventh root of x) times (the seventh root of x) times (the seventh root of x)

i.e. x^(1/7) times x^(1/7) times x^(1/7)

Using the formula, a^m times a^n = a^(m+n).

x^(1/7) times x^(1/7) times x^(1/7) = x^(1/7 + 1/7 + 1/7)

x^(1/7) times x^(1/7) times x^(1/7) = x^(3/7)

We can read it as "x to the 3 over seventh power".

Hence, option A is correct, i.e. x to the 3 over seventh power.
