Answer:
D (bottom right answer)
Step-by-step explanation:
The denominator of an exponent is the index of the root.
For example, x^1/2 means √2.
x^1/5 means the 5th root of x.
You have 3x^1/5.
3 is not in the root, so you need an answer that has a plain 3.
That eliminates the two answers on the top line.
Then you have x^1/5 which means the 5th root of x.
The correct answer must be 3 × 5th root of x
