The value of [dbc]a+[dca]b+[dab]c-[abc]d is

In a Delta ABC,2B=A+C and b^(2)=ac. Then the value of (a^(2)(a+b+c))/(3abc) is equal to

The minimum value of P=b c x+c a y+a b z , when x y z=a b c , is a. 3abc b. 6abc c. abc d. 4abc

The minimum value of P=b c x+c a y+a b z , when x y z=a b c , is a. 3abc b. 6abc c. abc d. 4abc

If a, b and c are non-coplanar vectors and d=lambdaa+mub+nuc , then lambda is equal to: a) ([dbc])/([bac]) b) ([bcd])/([bca]) c) ([bdc])/([abc]) d) ([cbd])/([abc])

If a=b^(x),(:b=c^(y) and backslash c=a^(z), then the value of xyz is equal to a.0 b.1 c.-1 d.abc

If abc=0 , then find the value of ([(x^(a))^(b)]^(2c))/(x^(abc))

Let A, B, C, D be (not necessarily ) real matrices such that A^(T) = BCD , B^(T) =CDA, C^(T) = DAB and D^(T) =ABC for the matrix S = ABCD the least value of k such that S^(k) = S is
