[tex]A = \binom{1 \: \: 6}{2 \: \: 4} [/tex]
[tex] {A}^{ - 1} = ...[/tex]
Penyelesaian:
[tex]A = \binom{1 \: \: 6}{2 \: \: 4} \\ {A}^{ - 1} = \frac{1}{a.d - b.c} \binom{1 \: \: 6}{2 \: \: 4} \\ {A}^{ - 1} = \frac{1}{4 - 12} \binom{1 \: \: 6}{2 \: \: 4} \\ {A}^{ - 1} = \frac{1}{ - 8} \binom{1 \: \: 6}{2 \: \: 4} \\ {A}^{ - 1} = \binom{ - \frac{ 1}{8} \: \: - \frac{3}{4} }{ - \frac{1}{4} \: \: - \frac{1}{2} }[/tex]
