" (ii) "x^(b)y^(c)z^(a)=x^(c)y^(a)z^(b)

If a(y+z)=b(z+x)=c(x+y) then show that (a-b)/(x^(2)-y^(2))=(b-c)/(y^(2)-z^(2))=(c-a)/(z^(2)-x^(2))]

If (logx)/(b-c)=(logy)/(c-a)=(logz)/(a-b) , then which of the following is/are true? z y z=1 (b) x^a y^b z^c=1 x^(b+c)y^(c+b)=1 (d) x y z=x^a y^b z^c

Show that the following system is inconsistent. (a-b)x+(b-c)y+(c-a)z=0 (b-c)x+(c-a)y+(a-b)z=0 (c-a)x+(a-b)y+(b-c)z=1

If a/(y+z) = b/(z + x) = c/(x+y) , then prove that (a(b-c))/(y^(2)-z^(2)) = (b(c-a))/(z^(2)-x^(2)) = (c(a-b))/(x^(2)-y^(2)) .

Without expanding, show that "Delta"=|(a-x)^2(a-y)^2(a-z)^2(b-x)^2(b-y)^2(b-z)^2(c-x)^2(c-y)^2(c-z)^2|=2(a-b)(b-c)(c-a)(x-y)(y-z)(z-x)

Without expanding, show that "Delta"=|(a-x)^2(a-y)^2(a-z)^2(b-x)^2(b-y)^2(b-z)^2(c-x)^2(c-y)^2(c-z)^2|=2(a-b)(b-c)(c-a)(x-y)(y-z)(z-x)

Prove that |(b+x)(c+x)(v+x)(a+x)(a+x)(b+x)(b+y)(c+y)(c+x)(a+t)(a+y)(b+y)(b+z)(c+z)(c+z)(a+z)(a+z)(b+z)|=(b-c)(c-a)(y-z)(x-y)dot

If (y/z)^a (z/x)^b (x/y)^c=1 , then prove that (y/z)^((1)/(b-c))=(z/x)^((1)/(c-a))=(x/y)^((1)/(a-b)) .
