Write the additive inverse of matrices A, B and C: Where A=[6-5];B=[-204-1] and C=[-74]. - Mathematics

प्रश्न

Write the additive inverse of matrices A, B and C:

Where $A = [\begin{matrix} 6 & - 5 \end{matrix}]; B = [\begin{matrix} - 2 & 0 \\ 4 & - 1 \end{matrix}]$ and $C = [\begin{matrix} - 7 \\ 4 \end{matrix}]$ .

उत्तर

We know additive inverse of a matrix is its negative.

Additive inverse of A = –A = $- [\begin{matrix} 6 & - 5 \end{matrix}] = [\begin{matrix} - 6 & 5 \end{matrix}]$

Additive inverse of B = –B = $- [\begin{matrix} - 2 & 0 \\ 4 & - 1 \end{matrix}] = [\begin{matrix} 2 & 0 \\ - 4 & 1 \end{matrix}]$

Additive inverse of C = –C = $- [\begin{matrix} - 7 \\ 4 \end{matrix}] = [\begin{matrix} 7 \\ - 4 \end{matrix}]$
