Prove that: `(log_9 11)/(log_5 3) = (log_3 11)/(log_sqrt(5) 3).`

Prove that (log_(2)8)/(log_(3)9) =3/2

Show that log_(3) 9+ log_(3) 3= log_(5) 125

Prove that log_3log_2log_(sqrt3) 81=1

let N =(log_(3) 135/log_(15) 3) - (log_(3) 5/log_(405) 3) , then N equals

Evaluate : (log 27)/( log sqrt3)

Compute the following (81^(1/((log)_5 9))+3^(3/((log)_(sqrt(6))3)))/(409)dot((sqrt(7))^(2/((log)_(25)7))-(125)^((log)_(25)6))

Prove that: log_3log_2log_(sqrt(5))(625)=1
