Answer:
63
Step-by-step explanation:
Based off of the question,we have a word problem that can be interpreted as the following. 6²+3³= ?
6² is the same as 6×6 which is equal to 36, In other words 6×6=36 or 6²=36
3³ is the same as 3×3×3 which is equal to 27, In other words 3×3×3=27 or
3³=27
Now with the product of each value in the word problem we can set up a statement as the following: 36+27= ?
Which when added together gives us the sum of 63, in other terms 36+27=63
concluding in our answer for the initial word problem. (6²+3³=63)

Answer:
48
Step-by-step explanation:
The fraction who picked apples is the rest of the students:
1 - 5/8 = 3/8
of them.
So the number who picked apples relative to the number who picked bananas is ...
apples/bananas = (3/8)/(5/8) = 3/5
Multiplying this by the number who picked bananas gives the number who picked apples:
apples = bananas · 3/5 = 80·3/5 = 48
48 students picked apples.
____
<em>Alternate solution</em>
Let "a" represent the number who picked apples. The ratio of banana choosers to the total is 5/8, and there were 80 who chose bananas. That gives rise to the equation ...
80/(80 +a) = 5/8
640 = 400 +5a . . . . . . multiply by 8(80+a) and simplify
240 = 5a . . . . . . . . . . . subtract 400
240/5 = a = 48 . . . . . . divide by 5
48 students picked apples.
