Find the value of the determinant
`|{:(1,2,4),(3,4,9),(2,-1,6):}|`

Find the value of the determinant |{:(-1,2,1),(3+2sqrt(2),2+2sqrt(2),1),(3-2sqrt(2),2-2sqrt(2),1):}|

Evaluate the determinant Delta = {:|(1,2,4),(-1,3,0),( 4,1,0)|:}

Expand |{:(1,2,3),(4,6,2),(5,9,4):}|

Evaluate the determinant. {:[( 2,4),( -5,-1) ]:}

Find the minor and cofactors of all the elements of the determinants {:|( 1,-2),(4,3)|:}

The value of the determine : Delta=|(1!,2!,3!),(2!,3!,4!),(3!,4!,5!)| is :

Find the minor of elements 6 in the determinants Delta = {:|( 1,2,3),(4,5,6),(7,8,9)|:}

Evaluate the following determinants: (a) |(2,4),(-5, -1)|

There are two values of a which makes determinant , A=|(1,-2,5),(2,a,-1),(0,4,2a)|=86 , then sum of these numbers is :

Find the value of x if, |(2,4),(5,1)| = |(2x, 4),(6, x)|
