Question

The product of two positive numbers is 16. Find the numbers if the sum is least.

Answer 1

only 3 things can multiply together to equal 16
1 x 16 = 16
4 x 4 = 16
8 x 2 = 16
if those pairs of numbers were added together which would give the smallest sum?
1 + 16 = 17
4 + 4 = 8
8 + 2 = 10
therefore 4 and 4 are the two numbers that give the smallest sum and are both multipliable to 16

Answer 2

can you show me the equation blackmamba..

Answer 3

I dont know if there is an equation to solve it in one step
but the method I showed you above gives the right answer

Answer 4

Do you know calculus? You can show that if you optimize a box with side lengths x and y, you get that x=y is the optimized length.
