Given that y is inversely proportional to #x^n# and k as the constant of proportionality ; a)(i)Write down a formula connecting y,x,n and k. (ii)If x=2 when y=12 and x=4 when y=3,write down two expressions for k in terms of n.Hence,find the value of n and k.
b).Using the values of n and k obtained in (a)(ii) above,find y when #x=5 1/3#.
