Geometry: Be at the back of the room, ready to go. I will be working with you first today. Algebra: Answer and turn the following problems in. Turn the following problems into radical form. 1) 5 3/4 2) 6 8/9 3) 7 2/3 4) I have answer keys from Monday’s work by the pencil sharpener. Take one and check your work. If you have an answer wrong. Figure out why and correct it.
Logarithms (at last!) • What do we know about logarithms?
Logarithms: Exponents in Reverse “Seven to the power of what equals 49?”
Let’s Try: Write in Logarithmic Form 1) 82 = 64 2)25 = 32 3) 34 = 81
We can also go the opposite way! Change the following from logarithm form to exponent form. 1) log4 16 = 2 2) log5 125 = 3 3) log10 1000 = 3
Add in x log2 8 = x
Try: • log6 216 = x 2) log3 27 = x
