Question

Find two positive numbers whose product is 81 and whose sum is a minimum. (if both values are the same number, enter it into both blanks.)

Answer 1

9 and 9; 3 and 27; 1 and 81; 40.5 and 2;

Answer 2

Answer:

The two positive numbers whose product is 81 and whose sum is a minimum are 9 and 9.

Step-by-step explanation:

81 is divisible by 1 and 81, since 81/1 = 81 and 81/81 = 1.

81 is divisible by 3 and 27, since 81/3 = 27 and 81/27 = 3.

81 is divisible by 9, since 81/9 = 9.

Their sums are.

81 + 1 = 82.

3 + 27 = 30

9 + 9 = 18.

So the two positive numbers whose product is 81 and whose sum is a minimum are 9 and 9.
