svp [43]

Answer:

(i)

x \alpha y {3} \\ \frac{x}{y {3} }  = k

(ii)

\frac{x}{y {3}^{} }  =  \frac{x}{y {3}^{} }  \\  \frac{32}{ {2}^{3} }  =  \frac{x}{6 {}^{3} }  \\  \frac{32}{8}  =  \frac{x}{216} \\ x = 864

(iii)

\frac{32}{8}  =  \frac{108}{y {}^{3} }  \\   {y}^{3 }  = 27 \\ y =  \sqrt[3]{27 }  \\ y = 3
