Best answer 6 votes 6 votes $Let, AB^{T}C^{-1} = X. $ $AB^{T}C^{-1}C = XC $ $AB^{T} = XC $ $|AB^{T}| = |XC| $ $|A| |B^{T}| = |X| |C| $ $|A| |B| = |X| |C| $ $8*3 = |X| * 6 $ $4 = |X|$ Akhilesh Singla answered Apr 22, 2018 • selected Feb 28, 2019 by Rishi yadav Akhilesh Singla comment Share Follow See all 0 reply Please log in or register to add a comment.
