Answer:
Step-by-step explanation:
Let x and y are the two positive real numbers
product of two numbers is 21
The sum of the two numbers is f(x) =x+y
Replace y with 21/x
we need to find smallest possible sum , so we take derivative using power rule
when sum is minimum then the derivative is equal to 0
multiply both sides by x^2
Take square root on both sides
