Good Morning, Precalculus!

When you come in, please....1. Grab your DO NOW sheet at the front of the room.2. Take out your homework from last night: pg. 708 #8 and 93. Start your DO NOW!

Do Now:Write the logarithmic expression you would use to represent each sentence. Then, solve for the unknown value.

1. What exponent would you raise 3 to if you wanted to get 81 as your answer?

2. Four raised to what power equals 1024?

Today's Agenda:1. Do Now2. Today's Objective3. Continuing Unit 4, Obj. 2: Properties of Logarithms4. Carousel Activity: Practicing the Properties of Logarithms5. Exit Slip6. ClosingHAVE A GREAT THANKSGIVING!!

Today's ObjectiveUnit 4, Objective 2: I will be able to write

logarithmic expressions in exponential form and vice versa.

Day 2

Continuing Unit 4, Obj. 2: Properties of Logarithms

Properties of LogarithmsPg. 720

How can you summarize the information on the table?

Properties of Logarithms

Ex. 1: Rewrite each logarithm using one of the logarithm properties.a. log48 - log46

b. log5

37

c. log4(x+2) = log46 d. 2log48

Properties of Logarithms

Ex. 1: Rewrite each logarithm using one of the logarithm properties.e. log21 + log24f.log5(8 *3)

g.log 8

23

Properties of LogarithmsEx. 2: Solve each logarithmic equation.

a. log4(2x+11) = log4(5x-4)b. log11x + log11(x+1) = log116

c. log6x + log69 = log654 d. log33x = log336

Properties of LogarithmsEx. 2: Solve each logarithmic equation.

e. log848 - log8w = log86f.

Carousel Activity: Practicing the Properties of Logarithms

Carousel Activity: Practicing the Properties of Logarithms

A couple of practice problems are written on the posters around the room.

With partner, move around the room at the given time intervals and complete the problems on the posters.

You will have 2.5 minutes to complete each poster.
