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
C. 69
.15 x 60 = 9 + 60 = 69
So basically you want to find the cost per day. So you have 5 days, so divide £100 by 5.
You get £20 per day
Now, the cost per child. We have 80 children so it would be £20/80 children per day.
Our answer is £0.25 per child per day.
