the product of two numbers is 220 and the sum of their squares is 289 . the sum of the number is ?
"let the numbers be x and y . then , xy = 220 and x 2 + y 2 = 289 . ( x + y ) 2 = x 2 + y 2 + 2 xy = 289 + ( 2 x 220 ) = 729 x + y = 27 . option c"
sqrt(add(power(sqrt(subtract(289, multiply(const_2, 220))), const_2), multiply(const_4, 220)))
