Answer:
250 boys attended the conference.
Step-by-step explanation:
First, divide 750 by 3 (one-third of the conference is boys) and you will get 250 (number of boys). If you wanted to find the number of girls too, you would simply double 250 to get 500 girls.
Using the power law (x^27 ⋅ y)^1/3 equals x^9 ⋅ x^1/3.
Raising a number to the 1/3 is the same as cube rooting.
So the simplified response is x^9(cube root of y).
answer: 2nd choice
