 log _3 11. log _(11)  13 = log _3 13  log _(13) 15.log _(15) 27 = log _(13) 27  ⇒log _3 (13).log _(13) (27)=log _3 (27)  ⇒log _3 (27).log _(27) (81)=log _3 (81)=4

log311.log1113=log313log1315.log1527=log1327log3(13).log13(27)=log3(27)log3(27).log27(81)=log3(81)=4

((log11)/(log3)).((log13)/(log11)).((log15)/(log13)).((log27)/(log15)).((log81)/(log27))  =((log81)/(log3))=log_3 81=4

log11log3.log13log11.log15log13.log27log15.log81log27=log81log3=log381=4

log_a  b=((ln b)/(ln a))  (log_3 11)(log_(11) 13)(log_(13) 15)(log_(15) 27)(log_(27) 81)  =((ln 11)/(ln 3))×((ln 13)/(ln 11))×((ln 15)/(ln 13))×((ln 27)/(ln 15))×((ln 81)/(ln 27))  =((ln 81)/(ln 3))  =((ln 3^4 )/(ln 3))  =((4×ln 3)/(ln 3))  =4

logab=lnblna(log311)(log1113)(log1315)(log1527)(log2781)=ln11ln3×ln13ln11×ln15ln13×ln27ln15×ln81ln27=ln81ln3=ln34ln3=4×ln3ln3=4
