Given `a=x//(y-z), b=y//(z-x),a n dc=z//(x-y),w h e r ex , y , za n dz` are not all zero, then the value of `a b+b c+c a` is `0` b. `1` c.`-1""` d. none of these

If (xy)/(x+y)=a,(xz)/(x+z)=b and (yz)/(y+z)=c where a,b,c are other than zero,find the value of x

Q.if x(y)/(x+y)=a,x(z)/(x+z)=b and y(z)/(y+z)=c, where a ,b and c are other than zero then x equals

If a , b , c , , x , y , z are 26 natural numbers, then the value of (x-a)(x-b)(x-c)ddot(x-y)(x-z) is (a) 0 (b) 1 (c) 13 (d) 26

The value of |[yz, z x,x y],[ p,2p,3r],[1, 1, 1]|,w h e r ex ,y ,z are respectively, pth, (2q) th, and (3r) th terms of an H.P. is a.-1 b. 0 c. 1 d. none of these

If x!=y!=za n d|[x,x^2, 1+x^3],[y ,y^2 ,1+y^3],[z, z^2, 1+z^3]|=0, then the value of x y z is a.1 b. 2 c. -1 d. 2

If x ,y ,a n dz are pth, qth, and rth terms, respectively, of an A.P. nd also of a G.P., then x^(y-z)y^(z-x)z^(x-y) is equal to a.x y z b. 0 c. 1 d. none of these
