If` a^p = b^q = c^r and b^2 = ac` then what is value of[ q(p+r)/pr ]

If p/a + q/b + r/c=1 and a/p + b/q + c/r=0 , then the value of p^(2)/a^(2) + q^(2)/b^(2) + r^(2)/c^(2) is:

If a !=p, b !=q, c!=r and |(p,b,c),(a,q,c),(a,b,r)| = 0 then the value of (p)/(p-a)+(q)/(q-b)+(r)/(r-c) is equal to a)-1 b)1 c)-2 d)2

If a!=p ,b!=q ,c!=ra n d|p b c a q c a b r|=0, then find the value of p/(p-a)+q/(q-b)+r/(r-c)dot

The incorrect statement is (A) p →q is logically equivalent to ~p ∨ q. (B) If the truth-values of p, q r are T, F, T respectively, then the truth value of (p ∨ q) ∧ (q ∨ r) is T. (C) ~(p ∨ q ∨ r) = ~p ∧ ~q ∧ ~r (D) The truth-value of p ~ (p ∧ q) is always T
