If a,b,c are in H.P., then the value of
`((1)/(b)+(1)/(c)-(1)/(a))((1)/(c)+(1)/(a)-(1)/(b))` is

If a,b,c are in H.P.tgen the value of ((1)/(b)+(1)/(c)-(1)/(a))((1)/(c)+(1)/(a)-(1)/(b))

If a,b,c are in H.P., then the value of ((1)/(b)+(1)/(c)-(1)/(a))((1)/(a)+(1)/(b)-(1)/(c)) is

If a,b,c are in H.P. then the expression E=((1)/(b)+(1)/(c)-(1)/(c))((1)/(c)+(1)/(a)-(1)/(b)) equals

If a, b, c are in H.P then ((1)/(b) + (1)/(c )-(1)/(a)) ((1)/(c ) + (1)/(a) - (1)/(b)) =

If a,b,c are in A.P. show that a((1)/(b)+(1)/(c)),b((1)/(c)+(1)/(a)), c((1)/(a)+(1)/(b)) are in A.P.

If a,b,c are in A.P then a((1)/(b) + (1)/(c )), b ((1)/(c ) + (1)/(a)), c ((1)/(a ) + (1)/(b)) are in

If a,b,c are in A.P.prove that: a((1)/(b)+(1)/(c)),b((1)/(c)+(1)/(a)),c((1)/(a)+(1)/(b)) are in A.P.

if a,b,c are in H.P., prove that ((1)/(a)+(1)/(b)-(1)/(c))((1)/(b)+(1)/(c)-(1)/(a))=(4)/(ac)-(3)/(b^(2))

If a,b,c are in H .P.then (1)/(a)+(1)/(b+c),(1)/(b)+(1)/(a+c),(1)/(c)+(1)/(a+b) are in

If a, b, c are in A.P. then show that, a((1)/(b)+(1)/(c )), b((1)/(c )+(1)/(a)) and c((1)/(a)+(1)/(b)) are also in A.P.
