the ratio of three numbers is 5 : 3 : 4 and their sum is 108 . the second number of the three numbers is ?
"5 : 3 : 4 total parts = 12 12 parts - - > 108 1 part - - - - > 9 the second number of the three numbers is = 3 3 parts - - - - > 27 b )"
sqrt(divide(108, add(power(4, 3), add(power(5, 3), power(3, 3)))))
