if the sum of two numbers is 16 and the sum of their squares is 200 , then the product of the numbers is
"according to the given conditions x + y = 16 and x ^ 2 + y ^ 2 = 200 now ( x + y ) ^ 2 = x ^ 2 + y ^ 2 + 2 xy so 16 ^ 2 = 200 + 2 xy so xy = 56 / 2 = 28 answer : e"
divide(subtract(power(16, const_2), 200), const_2)
