A logarithm looks like this A logarithm looks like this log2 8 = 3 A logarithm looks like this and has three parts log2 8 = 3 A logarithm looks like this and has three parts the base log2 8 = 3 A logarithm looks like this and has three parts the base base log2 8 = 3 A logarithm looks like this and has three parts the base, the argument log2 8 = 3 A logarithm looks like this and has three parts the base, the argument log2 8 = 3 argument A logarithm looks like this and has three parts the base, the argument, and the answer log2 8 = 3 A logarithm looks like this and has three parts the base, the argument, and the answer log2 8 = 3 answer base ? log2 8 = 3 argument ? answer ? The base is The argument is The answer is b ? logb a = c c ? a ? A logarithm is asking a question A logarithm is asking a question log2 8 = ? What exponent can be put on 2 A logarithm is asking a question log2 8 = ? What exponent can be put on 2 A logarithm is asking a question log2 8 = ? What exponent can be put on 2 to get 8? A logarithm is asking a question log2 8 = ? What exponent can be put on 2 to get 8? A logarithm is asking a question log2 8 = ? What exponent can be put on 2 to get 8? A logarithm is asking a question 21 = 2 log2 8 = ? What exponent can be put on 2 to get 8? A logarithm is asking a question 21 = 2 22 = 4 log2 8 = ? What exponent can be put on 2 to get 8? A logarithm is asking a question 21 = 2 22 = 4 log2 8 = ? 23 = 8 What exponent can be put on 2 to get 8? A logarithm is asking a question 21 = 2 22 = 4 log2 8 = ? 23 = 8 What exponent can be put on 2 to get 8? A logarithm is asking a question 21 = 2 22 = 4 log2 8 = ? 23 = 8 So the answer is 3 What exponent can be put on 2 to get 8? A logarithm is asking a question 21 = 2 22 = 4 log2 8 = 3 23 = 8 So the answer is 3 What exponent can we put on 3 to get 9? log3 9 = 1 2 3 4 log2 8 = log5 25 = Logarithms can be switched to exponential form. Logarithms can be switched to exponential form. log2 8 = 3 Logarithms can be switched to exponential form. log2 8 = 3 This is logarithmic form Logarithms can be switched to exponential form. 23 = 8 log2 8 = 3 Logarithms can be switched to exponential form. 23 = 8 log2 8 = 3 this is exponential form To change between the two just remember Logarithms can be switched to exponential form. 23 = 8 log2 8 = 3 To change between the two just remember Logarithms can be switched to exponential form. the base of the log becomes the base of the exponent 23 = 8 log2 8 = 3 To change between the two just remember Logarithms can be switched to exponential form. the base of the log becomes the base of the exponent the argument becomes the answer 23 = 8 log2 8 = 3 To change between the two just remember Logarithms can be switched to exponential form. the base of the log becomes the base of the exponent the argument becomes the answer 23 = 8 log2 8 = 3 To change between the two just remember Logarithms can be switched to exponential form. and the answer becomes the exponent the base of the log becomes the base of the exponent the argument becomes the answer 23 = 8 log2 8 = 3 Switch to exponential form Log3 9 = 2 3 = Switch to exponential form Log4 16 = 2 2 = Switch to logarithmic form 53 = 125 log5 = |
