When multiplying numbers of the same base , we add the powers. Example: 2^2 * 2^3 = 2^(2+3) = 2^5
For the givens: The seventh root of x can be written as x^(1/7) Now, we need to multiply x^(1/7) by x^(1/7) by x^(1/7) These numbers have the same base which is "x", therefore, we will just add the power. This means that: x^(1/7) * x^(1/7) * x^(1/7) = x^(1/7 + 1/7 + 1/7) = x^(3/7)
Therefore, the correct choice is the first one: x^(3/7)
