jika A =
[tex] \binom{1 \: \: \: \: \: \: 2}{3 \: \: \: \: \: \: \: 4} [/tex]
tentukan nilai A^-1​

A⁻¹ = 1/(Det A)[tex]\binom {1~~~~~2}{3~~~~~4}[/tex]

A⁻¹ = 1/(1.4 - 2.3)[tex]\binom {1~~~~~2}{3~~~~~4}[/tex]

A⁻¹ = 1/(4 - 6)[tex]\binom {1~~~~~2}{3~~~~~4}[/tex]

A⁻¹ = [tex]\large \bf{\binom{-\frac{1}{2}~~~~~-1}{-\frac{3}{2}~~~~~-2}}[/tex]
