jika A=(2 4 dibawah 1 3)maka A help me...

Invers Matriks

[tex]A = \left[\begin{array}{ccc}2&4\\1&3\end{array}\right] \\ \\ |A| = 6 - 4 = 2 \\ \\ Adj(A) = \left[\begin{array}{ccc}3&-4\\-1&2\end{array}\right] \\ \\ A^{-1} = \frac{1}{2} \left[\begin{array}{ccc}3&-4\\-1&2\end{array}\right] \\ \\ A^{-1} = \left[\begin{array}{ccc} \frac{3}{2} &-2\\- \frac{1}{2} &1\end{array}\right] [/tex]

Mohon koreksinya,

A = [ 2 4 ]
[ 1 3 ]
A^(-1) = [ 2^(-1) 4^(-1) ]
[ 1^(-1) 3^(-1) ]
= [ 1/2¹ 1/4¹ ]
[ 1/1¹ 1/3¹ ]
= [ 1/2 1/4 ]
[ 1 1/3 ]
