If pqr=1 show that
`(1)/(1+p+q^(-1))+(1)/(1+q+r^(-1))+(1)/(1+r+p^(-1))=1`

(1)/(1+p+q^(-1))+(1)/(1+q+r^(-1))+(1)/(1+r+p^(-1))=1, if pqr=1

If pqr = 1, then what is value of the expression (1)/(1+p+q^(-1)) +(1)/(1+q+r^(-1)) +(1)/(1+r+p^(-1)) ?

The value of 1/(p + q^(-1) + 1) + 1/(q + r^(-1) + 1) + 1/(1 + r + p^(-1)) given that pqr = 1 is :

If 5^(-p)=4^(-q)=20^(r) show that (1)/(p)+(1)/(q)+(1)/(r)=0

If y = (1)/(1+x^( p-r) +x^(q-r)) +(1)/( 1+ x^(p-q) +x^(r-q) )+ (1) /( 1+x^(q-p) +x^(r-p)),then (dy)/(dx) =

If 5^(-p)=4^(-q)=20^(r ) . Show that (1)/(p)+(1)/(q)+(1)/(r )=0
