If `a, b, c` are real numbers, then show that `root(5)(ab^-1)xxroot( 5)(bc^-1) xxroot( 5)(ca^-1) =1`.

If a,b,c are real numbers,then show that root(5)(ab^(-1))xx root(5)(bc^(-1))xx root(5)(ca^(-1))=1

root(5)(16)xxroot(5)(2) is equal t :-

Let a, b and c be positive real numbers. Then prove that tan^(-1) sqrt((a(a + b + c))/(bc)) + tan^(-1) sqrt((b (a + b + c))/(ca)) + tan^(-1) sqrt((c(a + b+ c))/(ab)) = pi

If a,b,c are positive real numbers,then (1)/(log_(a)bc+1)+(1)/(log_(b)ca+1)+(1)/(log_(c)ab+1)=

If a, b, c are positive real numbers, then (1)/("log"_(ab)abc) + (1)/("log"_(bc)abc) + (1)/("log"_(ca)abc) =

If a,b,c are in AP show that (i) 1/(bc) ,1/(ca),1/(ab) are in AP.

If a,b,c are real numbers such that 3(a^(2)+b^(2)+c^(2)+1)=2(a+b+c+ab+bc+ca) , than a,b,c are in

If a, b, c are positive real numbers then (1)/("1+log"_(a)bc) + (1)/("1+log"_(b)ca) +(1)/("1+log"_(c)ab)=

If a,b,c are non-zero real number such that |(bc,ca,ab),(ca,ab,bc),(ab,bc,ca)|=0, then
