Construct a 3×4 matrix A = [a_jj] whose elements a_jj are given by :

Let A = [a_ij]_2×3

So, the elements in a 3×4 matrix are

a₁₁, a₁₂, a₁₃, a_14, a₂₁, a₂₂, a₂₃,a₂₄,a_31,a_32,a_33,a₃₄

A = …… (1)

a₁₁ =

a₁₂ =

a₁₃ =

a₁₄ =

a₂₁ =

a₂₂ =

a₂₃ =

a_{24 =}

a₃₁ =

a₃₂ =

a₃₃ =

a₃₄ =

So, from (1)

A =
