Find two positive numbers whose product is 49 and whose sum is a minimum. (if both values are the same number, enter it into both blanks.) (smaller number) (larger number)

49       = 1 x 49
1 + 49 = 50

49   = 7 x 7
7+7 = 14

Hence 7 and 7 are the two positive numbers whose product is 49 and whose sum is minimum.

So the answer for the blanks is 7 and 7
