The two positive numbers whose sum is 16 and the sum of whose squares is minimum then the positive numbers are:
Solution
✅ Correct Option: 3
Let the two positive numbers be and .
Given constraints:
The sum of squares needs to be minimized:
From the constraint , express .
Substitute into the sum of squares:
To find the minimum, differentiate with respect to :
Set the derivative equal to zero:
Since and :
The sum of squares for various pairs with sum 16:
For :
For :
For :
For :
The minimum sum of squares is , achieved when both numbers equal .
Therefore, the two positive numbers are and .
