Find out correct order for the energy requried for heterolytic cleavage of indicated C-Br bonds forming carbocation :

Which of the followings are relations from {x, y, z} to {a, b, c, d} {a, b, c, d, x, y, z}

If in A B C , the distances of the vertices from the orthocentre are x, y, and z, then prove that a/x+b/y+c/z=(a b c)/(x y z)

Which of the followings are relations from {x, y, z} to {a, b, c, d} ,{(x, d),(y, b),(z, c)}

A person travels three equal distances at a speed of x km/hr, y km/hr and z knyhr respectively. What is the average speed for the whole journey? (x y z)/(3(x y+y z+z x)) b. (x y z)/((x y+y z+z x)) c. ((x y+y z+z x))/(x y z) d. (3x y z)/((x y+y z+z x))

Eliminate x,y and z from the following equations: (x)/(y+z)=a,y/(z+x)=b,z/(x+y)=c

If a,b,c,d are in GP and a^x=b^y=c^z=d^u , then x ,y,z,u are in

If aY+z)=b(z+x)=c(x+y) and out of a,b,c no two of them are equal then show that, (y-z)/(a(b-c))=(z-x)/(b(c-a))(x-y)/(c(a-b))
