The rules for the behaviour of exponents follow naturally from this definition First, let's try multiplying two numbers in exponential form For example 23 × 24 = (2 ×

Properties of Logarithms (Recall that logs are only defined for positive values of x.) For the natural logarithm For logarithms base a. 1. lnxy = lnx + lny. 1.
y is the exponent. The key thing to remember about logarithms is that the logarithm is an exponent! The rules of exponents apply to these and make simplifying
with exponentiation and conclude with a list of useful properties of exponents and logarithms. Exponentials. The value ax is called “a to the power of x” and

Use the properties of logarithms to expand the expression ln z as a sum difference
A logarithm is just another way to write an exponent. If you want to find out what is you multiply two fives together to get 25.
In the next few slides we discuss the behaviour of this function for different values of and . Base. Exponent or index. Page 11. 3.1.1
Since the exponential and logarithmic functions with base a are inverse functions the. Properties of Exponents give rise to the Properties of Logarithms.
Properties of exponents. Let a and b be positive numbers with a = 1 b = 1 and let x and y be real numbers. Then: A) Exponent Laws: 1. axay = ax+y. 2. (ax)y
Properties of Logarithms (Recall that logs are only defined for positive values of x.) For the natural logarithm For logarithms base a. 1. lnxy = lnx + lny. 1.

the inverse of an exponential function. Theorem 6.3. (Inverse Properties of Exponential and Log Functions) Let b > 0 b = 1.
y is the exponent. The key thing to remember about logarithms is that the logarithm is an exponent! The rules of exponents apply to these and make simplifying
If the logarithm is understood as the inverse of the exponential function then the properties of logarithms will naturally follow from our understanding of

many properties of exponents and logarithms shortly after they learn them and can seldom explain why these properties are true (Weber in press).
Because of this relationship it makes sense that logarithms have properties similar to properties of exponents. Properties of Logarithms. Let b
