Answer:
B and D
Step-by-step explanation:
B: 1/x^-1 means that you have to move the x to the opposite side of the fraction which makes it equal to x^1 which is just x.
D: x^(1/3) multiplied by itself three times is basically x^(1/3)^3. If you distribute the 3 to the first exponent, you get x^1 which also is equal to just x.
