Penjelasan dengan langkah-langkah

1. Diketahui:

\left[\begin{array}{ccc}2&1\\3&0\\\end{array}\right]x\left[\begin{array}{ccc}-2&0&2\\3&1&0\\\end{array}\right]

Ditanya: Hasil perkalian matriks 2x2 dengan 2x3?

Jawab:

\left[\begin{array}{ccc}2&1\\3&0\\\end{array}\right]x\left[\begin{array}{ccc}-2&0&2\\3&1&0\\\end{array}\right]

= \left[\begin{array}{ccc}2(-2)+1(3)&2(0)+1(1)&2(2)+1(0)\\3(-2)+0(3)&3(0)+0(1)&3(2)+0(0)\\\end{array}\right]

= \left[\begin{array}{ccc}-4+3&0+1&4+0\\-6+0&0+1&6+0\\\end{array}\right]

= \left[\begin{array}{ccc}-1&1&4\\-6&1&6\end{array}\right]

2. Diketahui:

A = \left[\begin{array}{ccc}0&1&2\\-2&0&3\end{array}\right]

B = \left[\begin{array}{ccc}4&2\\1&0\\3&-1\end{array}\right]

Ditanya: A x B?

Jawab:

A x B

=  \left[\begin{array}{ccc}0&1&2\\-2&0&3\end{array}\right] x  \left[\begin{array}{ccc}4&2\\1&0\\3&-1\end{array}\right]

=\left[\begin{array}{ccc}0(4)+1(1)+2(3)&0(2)+1(0)2(-1)\\-2(4)+0(1)+3(3)&-2(2)+0(0)+3(-1)\end{array}\right]

= \left[\begin{array}{ccc}4+1+6&0+0+(-1)\\-8+0+9&-4+0+(-3)&\end{array}\right]

= \left[\begin{array}{ccc}11&-1\\1&-7\end{array}\right]

3. Diketahui:

  • P = \left[\begin{array}{ccc}2&0\\1&3\end{array}\right]
  • Q= \left[\begin{array}{ccc}-1&1\\2&-3\end{array}\right]

Ditanya:Matriks hasil dariP^2-PQ-QP+Q^2?

Jawab:

Penjelasan lebih lengkap mengenai soal ini dapat dilihat di gambar terlampir.

P^2-PQ-QP+Q^2

= \\\left[\begin{array}{ccc}4&0\\5&9\end{array}\right] - \left[\begin{array}{ccc}-2&2\\7&10\end{array}\right] - \left[\begin{array}{ccc}1&3\\1&-9\end{array}\right] + \left[\begin{array}{ccc}3&2\\-7&-7\end{array}\right]

= \left[\begin{array}{ccc}4-(-2)-1+3&0-2-3+2\\5-7-1+(-7)&9-10-(-9)+(-7)\end{array}\right]

= \left[\begin{array}{ccc}8&-3\\-10&1\end{array}\right]

4. Diketahui: \left[\begin{array}{ccc}12&24\\48&36\end{array}\right]x\left[\begin{array}{ccc}16&32\\-24&-16\end{array}\right]

Ditanya: Hasil perkalian?

Jawab:

\left[\begin{array}{ccc}12&24\\48&36\end{array}\right] x  \left[\begin{array}{ccc}16&32\\-24&-16\end{array}\right]

= \left[\begin{array}{ccc}12(16)+24(-24)&12(32)+24(-16)\\48(16)+36(-24)&48(32)+36(-16)\end{array}\right]

= \left[\begin{array}{ccc}192+(-576)&384+(-384)\\768+(-864)&1536+(-576)\end{array}\right]

= \left[\begin{array}{ccc}-384&0\\-78&960\end{array}\right]
