How do you multiply the matrices #((2, 3), (1, -3))# with #((-1, 0, 2), (0, 2, 3))#?
1 Answer
Explanation:
Remember when multiplying matrices each entry in the product matrix are form by the corresponding
#=( (color(red)(2)(color(brown)(-1))+color(red)(3)(color(brown)(0)), color(red)(2)(color(cyan)(0))+color(red)(3)(color(cyan)(2)), color(red)(2)(color(orange)(2))+color(red)(3)(color(orange)(3))), (color(blue)(1)(color(brown)(-1))+(color(blue)(-3))(color(brown)(0)),color(blue)(1)(color(cyan)(0))+(color(blue)(-3))(color(cyan)(2)),color(blue)(1)(color(orange)(2))+(color(blue)(-3))(color(orange)(3))) )#
#=((-2,6,13),(-1,-6,-7))#
