If `A=[[3,4,5],[1,6,7],[2,8,3]]` ,then the value of `a_(21)A_(11)+a_(22)A_(12)+a_(23)A_(13)` is equal to

A=([5,1,2],[6,3,4]) find the value of a_(12)+a_(13)-a_(22)"

If A=[(1,1,0),(2,1,5),(1,2,1)] then a_(11)A_(21)+a_(12)A_(22)+a_(13)A_(23) is equal to

Let A = [ a_(ij) ] be a square matrix of order 3xx 3 and |A|= -7. Find the value of a_(11) A_(11) +a_(12) A_(12) + a_(13) A_(13) where A_(ij) is the cofactor of element a_(ij)

If A=[(1,2,1),(3,2,3),(2,1,2)] , then a_(11) A_(11)+a_(21) A_(21)+a_(31) A_(31)=

If A=[(3,2,4),(1,2,1),(3,2,6)] and A_(ij) are the cofactors of a_(ij) , then a_(11)A_(11)+a_(12)A_(12)+a_(13)A_(13) is equal to

IF A=[(1,1,0),(2,1,5),(1,2,1)], then a_(11) A_(21) +a_(12)A_(22)+a_(13)A_(23) =

If a_(n) is a geometric sequence with a_(1)=2 and a_(5)=18, then the value of a_(1)+a_(3)+a_(5)+a_(7) is equal to

In the matrix A=[[x,1],[1,0]] and A^4=[[109,a_(12)],[a_(21),a_(22)]] , then find the value of a_(22) is equal to

Given a_(1),a_(2),......,a_(12) are in G.P. If a_(4)*a_(9)=2019 then value of (a_(2)a_(11)+a_(3)a_(10)+a_(5)a_(8)+a_(6)a_(7))/(a_(4)a_(9)) is equal to

If a_(n) = 3-4n , then what is a_(1)+a_(2)+a_(3)+…+a_(n) equal to ?
