Asked by Jarin
the sum of N positive integers is 19. what is the maximum possible product of these N numbers?
thx.
Nice problem.
Let's look at some cases
1. N=2
clearly our only logical choices are 9,10 for a product of 90
It should be obvious that the numbers should be "centrally" positioned
e.g 2 and 17 add up to 19, but only have a product of 34
2. N=3
I considered 4,7,8 for a product of 224, 5,6,8 for a product of 240 and 2,8,9 for a product of only 144.
3. N=4
You should quickly realize that we can't start too high or we will go over 19
so 2,3,4,10 ---> product 240
2,3,5,9 ---> product 270
2,3,6,8 ---> product 288
3,4,5,7 ---> product 420 *!*!
4. N=5
We have to start with 1,2,3 or else we run over,
e.g. if we start with 2,3,4,5 we already have a sum of 14, so we need a 5, but we already used it.
so the only choices would be
1,2,3,4,9 ---> product 216
1,2,3,5,8 ---> product 240
1,2,3,6,7 ---> product 252
so it looks like the 4 numbers 3,4,5,7 which have a sum of 19 and a maximum product of 420 are it!
okay i get it!so you will just have to try out all the possible way!thanks for the help~
Do the numbers have to be different?

If the numbers can be repeated:
3*(2^8) = 768
3+(2*8) = 19
3*(2^8) = 768
3+(2*8) = 19

To find the product, we simply multiply the three numbers:
13 × (–5) × (–6) = 390
13 × (–5) × (–6) = 390

To find the quotient, we simply divide -14 by -2:
-14 ÷ (-2) = 7
Therefore, -14 ÷ (-2) = 7.
-14 ÷ (-2) = 7
Therefore, -14 ÷ (-2) = 7.

Let's simplify each expression to determine which pair has the same value:
A. (-2)(-7) = 14 and 4 + (-18) = -14, so A is not the correct answer.
B. (2)(7) = 14 and 4 + 18 = 22, so B is not the correct answer.
C. (-2)(7) = -14 and 18 + (-4) = 14, so C is the correct answer.
D. (2)(-7) = -14 and 4 - 18 = -14, so D is not the correct answer.
Therefore, the pair of expressions that has the same value is C, (-2)(7) and 18 + (-4).
A. (-2)(-7) = 14 and 4 + (-18) = -14, so A is not the correct answer.
B. (2)(7) = 14 and 4 + 18 = 22, so B is not the correct answer.
C. (-2)(7) = -14 and 18 + (-4) = 14, so C is the correct answer.
D. (2)(-7) = -14 and 4 - 18 = -14, so D is not the correct answer.
Therefore, the pair of expressions that has the same value is C, (-2)(7) and 18 + (-4).

To solve for x, we want to isolate x on one side of the equation. First, we add 3 to both sides of the equation to cancel out the -3 on the left side:
-3 + x + 3 = 11 + 3
Simplifying the left side, we get:
x = 14
Therefore, the solution to the equation -3 + x = 11 is x = 14.
-3 + x + 3 = 11 + 3
Simplifying the left side, we get:
x = 14
Therefore, the solution to the equation -3 + x = 11 is x = 14.

To solve for Q, we want to isolate Q on one side of the equation. First, we add 26 to both sides of the equation to cancel out the -26 on the left side:
Q - 26 + 26 = -53 + 26
Simplifying the right side, we get:
Q = -27
Therefore, the solution to the equation Q - 26 = -53 is Q = -27.
Q - 26 + 26 = -53 + 26
Simplifying the right side, we get:
Q = -27
Therefore, the solution to the equation Q - 26 = -53 is Q = -27.

To solve for b, we want to isolate b on one side of the equation. First, we multiply both sides of the equation by -8 to cancel out the fraction on the left side:
(-8) * start fraction lower b over negative 8 end fraction = -2 * (-8)
Simplifying the left side, we get:
b = 16
Therefore, the solution to the equation start fraction lower b over negative 8 end fraction = –2 is b = 16.
(-8) * start fraction lower b over negative 8 end fraction = -2 * (-8)
Simplifying the left side, we get:
b = 16
Therefore, the solution to the equation start fraction lower b over negative 8 end fraction = –2 is b = 16.

To solve for r, we want to isolate r on one side of the equation. First, we divide both sides of the equation by 6:
6r/6 = -48/6
Simplifying, we get:
r = -8
Therefore, the solution to the equation 6r = -48 is r = -8.
6r/6 = -48/6
Simplifying, we get:
r = -8
Therefore, the solution to the equation 6r = -48 is r = -8.

To find the total profit or loss for the four days, we need to add up the losses and profits for each day:
Loss on Thursday = $19
Loss on Friday = $12
Loss on Saturday = $11
Profit on Sunday = $15
To find the total profit or loss, we add up the amounts:
Total profit/loss = -19 - 12 - 11 + 15
Total profit/loss = -27 + 15
Total profit/loss = -12
Therefore, the total profit or loss for the four days is a loss of $12.
Loss on Thursday = $19
Loss on Friday = $12
Loss on Saturday = $11
Profit on Sunday = $15
To find the total profit or loss, we add up the amounts:
Total profit/loss = -19 - 12 - 11 + 15
Total profit/loss = -27 + 15
Total profit/loss = -12
Therefore, the total profit or loss for the four days is a loss of $12.
