#p=12#

We have:

#log_5(64)-log_5(8/3)+log_5(2)=log_5(4p)#

Let's first combine the left side:

#log_5((64xx2)/(8/3))=log_5(4p)#

#log_5((64xx2xx3)/(8))=log_5(4p)#

#log_5(8xx2xx3)=log_5(4p)#

#log_5(48)=log_5(4p)#

We can now take the inverse function (effectively getting rid of the logs):

#48=4p#

#p=12#
