if one positive integer is greater than another positive integer by 3 , and the difference of their cubes is 279 , what is their sum ?
"1 ^ 3 = 1 2 ^ 3 = 8 3 ^ 3 = 27 4 ^ 3 = 64 5 ^ 3 = 125 6 ^ 3 = 216 7 ^ 3 = 343 the two numbers are 4 and 7 . the answer is d ."
add(divide(add(power(3, 3), sqrt(add(power(power(3, 3), const_2), power(subtract(279, power(3, 3)), const_2)))), multiply(power(3, const_2), const_2)), subtract(divide(add(power(3, 3), sqrt(add(power(power(3, 3), const_2), power(subtract(279, power(3, 3)), const_2)))), multiply(power(3, const_2), const_2)), 3))
