If `A=[[3,0],[2,-4]]` and `kA=[[3a,0],[2b,12]]`,then the values of `k,a` and `b` are respectively

(A) `-3,2,4` (B) `-3,2,4` (C) `-3,3,2` (D) `-3,-3,-3`

If A={:[(0,2),(3,-4)]:}and kA={:[(0,3a),(2b,24)]:} , then the values of k,a,b are respectively.

If A=[(0, 2),( 3,-4)] and k A=[(0, 3a),(2b, 24)] , then the values of k ,\ a ,\ b , are respectively (a) -6, -12, -18 (b) -6, 4, 9 (c) -6, -4, -9 (d) -6, 12, 18

If A=[{:(0,2),(3,-4):}] and k A =[{:(0,3a),(2b,24):}], then find the value of b-a-k.

If A= [[1,2],[3,4]] , adjA= [[4,a],[-3,b]] , then the values of a and b are: (a) a=-2, b=1 (b) a=2, b= 4 (c) a=2, b=-1 (d) a=1, b=-2

The value of sin^3 10^0+sin^3 50^0-sin^3 70^0 is equal to (a) -3/2 (b) 3/4 (c) -3/4 (d) -3/8

If A=[[1,2,-3] , [5,0,2] , [1,-1,1]] and B=[[3,-1,2] , [4,2,5] , [2,0,3]] then find matrix C such that A+2C=B

Given A=[[1,2,-3],[5,0,2],[1,-1,1]] and B=[[3,-1,2],[4,2,5],[2,0,3]] , find the matrix C such that A+C=B.

If (z)/(2b)=4, (z)/(3c)=6, and 2b+3c=12 , what is the value of z?

Find the value of : 3abc-2a^2+4b^3+ac given that a=-2,b=3 and c=-1
