" 3.If "C=|[2,7,65],[3,8,75],[5,9,86]|" Find the determinant of "C

Prove that |[2,7,65],[3,8,75],[5,5,86]|=0

Write the value of |[2,7,65],[3,8,75],[5,9,86]|

Evaluate |(2,7,65),(3,8,75),(5,9,86)| .

Evaluate |[2, 7, 65],[ 3, 8, 75],[ 5, 9, 86]|=0

Write the value of |[2, 7, 65],[ 3, 8, 75],[ 5, 9, 86]|

Using the property of determinants and without expanding , prove that: |[2,7,65],[3,8,75],[5,9,86]| = 0

Without expanding the determinant prove the following. |[2,7,65],[3,8,75],[5,9,86]|=0

Using the property of determinants and without expanding, prove that: |[2, 7, 65],[ 3 ,8 ,75 ],[4, 9,86]|=0

If A = [(9, 1),(7,8)] and B = [(1,5),(7,12)] , find the matrix C such that 5 A + 3 B + 2 C is a null matrix.

Using the property of determinants and without expanding prove that abs([2,7,65],[3,8,75],[5,9,86])=0
