Let L 1 : ) k ˆ 2 j ˆ i ˆ ( r + − = G + λ ) k ˆ 2 j ˆ i ˆ ( + − , λ ∈ R, L 2 : ) k ˆ j ˆ ( r − = G + μ ) k ˆ p j ˆ i ˆ 3 ( + + , μ ∈ R, and L 3 : ) k ˆ n j ˆ m i ˆ ( r + + δ = A G , δ ∈ R be three lines such that L 1 is perpendicular to L 2 and L 3 is perpendicular to both L 1 and L 2 . Then the point which lies on L 3 is
