Question

alguém me ajuda nesse exercício pfv

Answer 1

Transposta de um matriz significa o inverso dela, se uma matriz é 3x2 sua transposta virar a ser 2x3.
mxn->nxm
m = nº de linhas -> n
n = nº de colunas -> m

a) $A_{22} =\left[\begin{array}{ccc}7&-4\\1&0\end{array}\right] \\ \\ A^t_{22}= \left[\begin{array}{ccc}7&1\\-4&0\end{array}\right]$

b) $B_{32}= \left[\begin{array}{ccc}6&2\\1&0\\4&-1\end{array}\right] \\ \\ B^t_{23}= \left[\begin{array}{ccc}6&1&4\\2&0&-1\end{array}\right]$

c) $C_{23}= \left[\begin{array}{ccc}0&3&-9\\0&-1&5\end{array}\right] \\ \\ C^t_{32}= \left[\begin{array}{ccc}0&0\\3&-1\\-9&5\end{array}\right]$

e) $E_{42}= \left[\begin{array}{ccc}0&-2\\1&11\\0,5&7\\3&4,1\end{array}\right] \\ \\ E^t_{24} \left[\begin{array}{cccc}0&1&0,5&3\\-2&11&7&4,1\end{array}\right]$

f) $F_{51} \left[\begin{array}{ccc}5\\7\\1\\0\\3\end{array}\right] \\ \\ F^t_{15}= \left[\begin{array}{ccccc}5&7&1&0&3\end{array}\right]$

g) $G_{33}= \left[\begin{array}{ccc}2&1&-2\\-3&1&2\\3&-1&2\end{array}\right] \\ \\ G^t_{33}= \left[\begin{array}{ccc}2&-3&3\\1&1&-1\\-2&2&2\end{array}\right]$

Answer 2

a) A=$\left[\begin{array}{cc}7&-4&1&0&\\\end{array}\right]$ b)B =$\left[\begin{array}{ccc}6&1&4&2&0&-1\\\end{array}\right]$ c) C=$\left[\begin{array}{ccc}0&3&-9&0&-1&5\end{array}\right]$ e) E=$\left[\begin{array}{cccc}0&1&0,5&3&-2&11&7&4,1\end{array}\right]$ f) F=$\left[\begin{array}{ccccc}5&7&1&0&3&&&\end{array}\right]$ g)G=$\left[\begin{array}{ccc}2&-3&3&1&1&-1&-2&2&2\end{array}\right]$
