If `a,b,c` are the `p^(th), q^(th), r^(th)` terms in H.P. then `|(bc,p,1),(ca,q,1),(ab,r,1)|=`

If a,b, c are pth, qt, rth terms of a H.P then |(bc,ca,ab),(p,q,r),(1,1,1)|=

If a,b,c be respectively the p^(th),q^(th)andr^(th) terms of a H.P., then Delta=|{:(bc,ca,ab),(p,q,r),(1,1,1):}| equals

If a,b,c be respectively the p^(th),q^(th)andr^(th) terms of a H.P., then Delta=|{:(bc,ca,ab),(p,q,r),(1,1,1):}| equals

If a,b,c are p^(pt),q^(th) and r^(th) terms of an A.P., find the value of |(a,b,c),(p,q,r),(1,1,1)| .

If a^(-1), b^(-1), c^(-1) are p^(th),q^(th) and r^(th) terms of an AP then the value of |(bc,ca,ab),(p,q,r),(1,1,1)| is

If a, b and c are respectively the p^(th) , q^(th) and r^(th) terms of an A.P., then |(a" "p" "1),(b" "q" "1),(c" "r" "1)|=

If a b c are the p^(th),q^(th) and r^(th) terms of an AP then prove that sum a(q-r)=0

If l, m, n are the p^(th), q^(th), r^(th) terms of a G.P which are +ve, then |(log l,p,1),(log m ,q,1),(log n ,r,1)|=

If a,b,c are all positive, and are p^(th), q^(th) and r^(th) terms of a G.P., show that |("log"a,p,1),("log"b,q,1),("log"c,r,1)|=0 .
