Expand the following expression: log3 P^3/R
=log3 p^3 - log3 R
=3log3P - log3R
log3 27=x
or log3 3^3=x
or 3 log3 3=x
or 3 * 1=x
ie x=3
logx 4=2/3
or (3/2)logx 4=1
or logx 4^(3/2)=1
or logx 8=1=log8 8
ie x=8
logb x= 3logb 2+1/2 logb 25-logb 20
or logb x=logb 2^3 +logb 25^1/2 -logb 20
or logb x=logb 8 + logb 5 -logb 20
or logb x=logb 8*5/20
= logb 2
ie x=2
