Question

for what value of x the matrix [(0 2 -3) (-2 0 -4) (3 4 x+5)]is skew matrix

Answer 1

Answer:

Therefore, for x=1 the matrix A is skew symmetric. Note:While multiplying any constant to a matrix we have multiplied this constant to every element of the matrix.

Answer 2

Answer:

The value of x is -5

Step-by-step explanation:

If the transpose of a matrix is equal to the negative of itself, the matrix is said to be skew symmetric matrix . It should be in a square then it is skew symmetric.

from the above added pic,

$A=- {A}^{t}$

$x + 5 = - (x + 5)$

$2(x + 5) = 0$

$x + 5 = 0$

$x = - 5$

Therefore the value of x is -5
