If `|(a,b),(c,d)| = k|(c,d),(a,b)|`, then the value of k is
(i) `0 ` (ii)`-1`

If ( a times b)*(c times d)=(a*c)(b*d)+k(a.d)(b.c) then the value of k is

If (a)/(b+c)=(b)/(c+a)=(c)/(a+b)=K, then the value of K is +-(1)/(2)(b)(1)/(2) or -1(c)-1(d)(1)/(2)

If |(a^2,b^2,c^2),((a+b)^2 ,(b+1)^2,(c+1)^2),((a-1)^2 ,(b-1)^2,(c-1)^2)| =k(a-b)(b-c)(c-a) then the value of k is a. 4 b. -2 c.-4 d. 2

If (a times b) times (c times d)=[a b d]c+kd then the value of k is

If 1.125xx10^(k)=0.001125, then the value of k is: -4(b)-3(c)-2(d)-1

If (a+b)/(c)=(b+c)/(a)=(c+a)/(b)=k, then k is equal to 0 b.1 c.2 d.a+b+c

If A and B be two complex numbers such that |1-A'B|^(2)-|A-B|^(2)=K(1-|A|^(2))(1-|B|^(2)) then the value of k is (A)1(B)2(C)(1)/(2)(D)(1)/(3)

Let A=[(0, alpha),(0,0)] and (A+I)^(50) -50A=[(a,b),(c,d)] . Then the value of a+b+c+d is
