Brainliest would be appreciated :))
When an exponent is a fraction, the denominator is written as a root, while the numerator is the power:
Since a is to the power of 5/7, the 7 becomes the 7th root, and the 5 becomes a^5. This is:
7th root of (a^5), or(B).

Answer:
20 chairs
Step-by-step explanation:
Since we are given the amount total budget and the total amount for the desks then the only variable missing is the maximum amount of chairs. This can be solved with the following equation in which s represents the number of chairs, and we simply solve for s.
800 = 320 + 24s ... subtract both sides by 300
500 = 24s ... divide both sides by 24
20.83 = s
Now we see that the maximum number of chairs that the librarian can buy is 20 because 21 would make her go over the budget and you cannot have 0.83 of a chair.
Use distributive property: a(b + c) = ab + ac.
2(w + 7) + 6(3w - 1) = (2)(w) + (2)(7) + (6)(3w) + (6)(-1)
= 2w + 14 + 18w - 6
<em>combine like terms</em>
= (2w + 18w) + (14 - 6) = 20w + 8
<h3>Answer: 2(w + 7) + 6(3w - 1) = 20w + 8</h3>
