1.4.3 Matrix Transformations

Condition: Matrices are given. \ [\ begin {aligned} a & = \ left (\ begin {array} {cccc} 2 & 4 & 3 & &8 & -2 & 2 &2 & 2 & 6 \ End {Array} \ Right), K = \ left (\ begin {array} {ccc} 5 & 6 & 0 & &3 &3 \\ 1 & 4 & -7 \ end {Array} \ Right) \\ C & = \ LEFT (\ Begin {Array} {CCC} {CCC} 2 & 0 & 2 \\ 0 & -1 & -3 \\ 3 & 4 & 1 \ End {Array} \ Right). \ end {aligned} \] calculate \ (a (2 c-4 k) \).
