Let w=zzˉ+k1z+k2iz+λ(1+i),k1,k2∈Rw=z \bar{z}+k_{1} z+k_{2} i z+\lambda(1+i), k_{1}, k_{2} \in \mathbb{R}w=zzˉ+k1​z+k2​iz+λ(1+i),k1​,k2​∈R. Let Re⁡(w)=0\operatorname{Re}(w)=0Re(w)=0 be the circle C\mathrm{C}C of radius 1 in the first quadrant touching the line y=1y=1y=1 and the yyy-axis. If the curve Im⁡(w)=0\operatorname{Im}(w)=0Im(w)=0 intersects C\mathrm{C}C at A\mathrm{A}A and B\mathrm{B}B, then 30(AB)230(A B)^{2}30(AB)2 is equal to ‾\underline{\hspace{2cm}}​
