Question

1. (a) Construct the matrix Upper A equals left bracket Upper A Subscript ij right bracketA=Aij if A is 2*3 and

Upper A Subscript ij Baseline equals negative i plus 4 jAij=−i+4j.

​(b) Construct the 2*4 matrix Upper C equals left bracket left parenthesis 3 i plus j right parenthesis squared right bracketC=(3i+j)2.

2.

Solve the following matrix equation.

left bracket Start 2 By 2 Matrix 1st Row 1st Column 3 x 2nd Column 4 y minus 5 2nd Row 1st Column z 2nd Column 4 w EndMatrix right bracket equals left bracket Start 2 By 2 Matrix 1st Row 1st Column 12 2nd Column 10 2nd Row 1st Column 8 2nd Column 16 EndMatrix right bracket
