## Cacastro one year ago The product is 192 and the sum is minimum.

1. Arfney

at least what? The lowest value it can be?

2. mary.rojas

so yeah the lowest value..... well start off by listing all the possible pairs that have a product of 192

3. mary.rojas

sooo... like 12*16 and continue on

4. Arfney

I would break it down into prime numbers, and then use the entire list of prime numbers and multiply them together to make two numbers that make up 192. Then after a few you should have all of the numbers that could make up in a chart, and you can pick the two that add up to make the lowest number.

x times y =192$\rightarrow$ y=192/x x+y=s $\rightarrow$ x+(192/x)=s ,, and then dervive both sides when you know s is a constant you get x=$\sqrt{192}$ is a local and absolute minimum

lol this question is from a week ago
