   Introduction to Logarithms. -A logarithm is the inverse function for an exponent; therefore, we will review exponential functions first. Review of Exponential Functions. -An exponential function has the general form ( ) = , where 0 < -b is called the base and x is called the exponent. < 1, or > 1.

   What does it mean? First of all the assumptions (restrictions) are important. The number a, called the base of the logarithm, has to be greater than 0 and cannot be equal to 1. The number b (which we take the logarithm of) has to be greater than 0. We have the following de nition of logarithms: De nition. a > 0, a 6= 1 and b > 0 we have:

   This topic introduces logarithms and exponential equations. Logarithms are used to solve exponential equations, and so are used along with exponential functions when modelling growth and decay. The logarithmic function is an important mathematical function and you will meet it again if you study calculus.

   Logarithms make a lot of people anxious. A lot of this has to do with the way they're often taught in high school and secondary school: by memorizing all the proper steps, without imparting much deeper meaning. For example, maybe you were once taught to solve problems like this: log7 49 = ?

   1.1 Introduction Whenever we use expressions like 73 or 25 we are using exponents. The symbol 25 means 2×2×2×2×2 5 factors. This symbol is spoken as ‘two raised to the power five’, ‘two to the power five’ or simply ‘two to the five’. The expression 25 is just a shorthand way of writing ‘multiply 2 by itself 5 times’.

   University of Sydney 1 Logarithms. 1.1 Introduction. Taking logarithms is the reverse of taking exponents, so you must have a good grasp on exponents before you can hope to understand logarithms properly. We begin the study of logarithms with a look at logarithms to base 10.
