In her Algebra II Class , Mrs. Pemdas writes the following statement on the board: " a varies inversely as the product of b^2 and c , and directly as d^3 . " She then asks her students to translate the statement into an equation . What of the following equations , with k as the constant of proportionality , is a correct translation of Mrs. Pemdas's statement ?
