Turn in your Quiz!!! Complete the following:

Section 11-5: Common Logarithms The questions are… What is a common log? How do I evaluate common logs? What is an antilog? How do I evaluate logs in bases other than 10 and e? So what are these logs good for and how do I use them?

What is a common log?

How do I evaluate common logs?

What is an antilog? Just another name for an exponential function with a base of 10.

How do I evaluate logs in bases other than 10 and e?

Change of base formula

Try this…

So what are these logs good for and how do I use them? Let’s try some from p 731

Solving by graphing
