Question 710592
log 3^3 -log 3^-2 + (log 51 -log 17  over log 81- log 3^2)+ 4 log 3^-1 + log 3^3
=log (3^3/3^-2) + (log 51/17 over log (81/9)) + log 3^-4 +log 3^3
= log 3^5 + log (3) over 2 log 3 )+ log (3^-4 *3^3)
 = log 3^5 + log 3 /2 log 3  + log (3^(-4+3))
=log 3^5 + 1/2 +log 3^-1
= 5 log 3 +1/2 -log 3
=4log 3 +0.5
