A farmer F1 has a land in the shape of a triangle with vertices at P(0,0),Q(1,1) and R(2,0) . From this land, a neighbouring farmer F2takes away the region which lies between the side 𝑃𝑄 and a curvof the e y=xn(n>1) . If the area of the region taken away by the farmer F2 is exactly 30% of the area of ΔPOR , then the value of n is
