(a)   Estimate the population of the town in 2020. Show your work.

 

 

2.   Convert the following single log statements into 5 log statements separated by + and – signs.

Log (a3b4)/(6cd) )

NOTE:  You must show this in at least two steps.

1st line should be to convert the 3 and the 4 only.

2nd line can be the final answer.

NOTE:    6cd is all in the denominator.
