The square of a is directly proportional to the cube of b. Which of the following equations correctly expresses this relationship?

Question

a. b2,a³ =k

b. b³,a²=k

c. a³,b²=k

d. a²,b³=k

Answer 1

a^2 =kb^3

a^2/b^3 =k

a^2b^-1 =k

a) and c) are wrong

d) looks likely if there's a misprint

c) and d) also wrong but they're what a computer program might mark correct. odds are d) is "best" answer
