1.	If l,m and n are the pth, qth and rth terms of a G.P. and are all positive, then ∣∣∣∣lnlp1lnmq1lnnr1∣∣∣∣ equals to
Answer» If $l, m$ and $n$ are the $p^{t h}$ , $q^{t h}$ and $r^{t h}$ terms of a G.P. and are all positive, then $∣ ∣∣ ∣ \begin{matrix} ln l & p & 1 ln m & q & 1 ln n & r & 1 \end{matrix} ∣ ∣∣ ∣$ equals to
