Question

a,b,c are three number. Such that x to the power of a = y to the power of b = z to the power of c.
Prove that 1/x,1/y,1/z are in arithmetic progression when b square = ac 
                                                

Answer 1

take log on both the sides this is the first method if u have studied logarithm or else if u have not studied logarithm then assume the whole expression to be some constant k and the problem will be simpler from there....express each of the given entity in the form of k
