`(-11)+(-2)+(-1)=` ___________

The HCF of (a^(2) +1) (a +11) and (a^(2) +1)^(2) (a +11)^(2) is _____

The foot of perpendicular from (-1,2,3) on the plane passing through the points (1,-1,1),(2,1,-2) and (3,-1,1) is:

If A=[(2,-1,1),(-1,2,-1),(1,-1,2)] show that A^(2)-5A+4I=0 Hence find A^(-1)

ABC is a triangle and AD is the median. If the coordinates of A are (4,7,-8) and the coordinates of centroid of triangle ABC are (1,1,1) what are the coordinates of D? (A) ((-1)/2,2,11) (B) ((-1)/2,-2,11/2) (C) (-1,2,11) (D) (-5,-11,19)

if [{:(3,2),(7,5):}]A{:[(-1,1),(-2,1):}]={:[(2,-1),(0,4):}] then trace of A is equal to

If A^(-1)=([2,1],[1,1]) ,then A is equal to: (A) ([2,-1],[-1,1]) (B) ([-2,1],[-1,-1]) (C) ([1,-1],[-1,2]) (D) ([-2,1],[1,1])

If A+B=[(1,0),(1,1)] and A-2B=[(-1,1),(0,-1)] then A= (A) 1/3 [(1,1),(2,1)] (B) 1/3 [(2,1),(1,2)] (C) [(1,1),(2,1)] (D) none of these

If A=[(1,0),(1,1)], B=[(2,0),(1,1)] and C=[(-1,2),(3,1)], show that

What will come in place of question mark (?) . sqrt(11) + ((11))^(1//2) = ?

Find the vector and cartesiooan equations of the plane passing through the points A(1,1-2),B(1,2,1),C (2,-1,1)
