Answer: x^3/3
Explanation:
Since you have an exponent outside of your 'x' in parenthesis, you're multiplying the exponents together, that being 1 * 3.
Since the exponent of 3 is being multiplied to only the top area, your 3 stays the same, leaving you with x^3/3
If the exponent is being multiplied to the top and bottom, your answer would be x^3/3*3*3 or x^3/27.
Hope this helps!
