1/(4i)^2 = 1/(15  8i)
multiply by the conjugate ( 15+8i)
(15+8i)/ 289 = 15/289 + 8i/289

But about the argand plane.. i have to change the equation to cartesian form first rite??

no in order to draw it on argand plane you only need the x + iy format and the point is (x,y) understand

So bascially the point you will get is (15/289 , 8/289)
