EXPONENT RULES & PRACTICE 1. PRODUCT RULE: To multiply when two bases are the same, write the base and ADD the exponents. Examples: A. B. C. 2. QUOTIENT RULE: To divide when two bases are the same, write the base and SUBTRACT the exponents. Examples: A. B. ˘ C. ˇ ˇ 3.
Express the equation in exponential form and solve the resulting exponential equation. Simplify the expressions in the equation by using the laws of logarithms.

we need to have some understanding of the way in which logs and exponentials work. De nition: If x and b are positive numbers and b 6= 1 then the logarithm of x to the base b is the power to which b must be raised to equal x. It is written logb x. In algebraic terms this means that if y = logb x then x = by

Sometimes you need to write an expression as a single logarithm. Use the rules to work backwards. Example 6 Write 2 log 3 x + log 3 y as a single logarithm log 3 x 2 + log 3 y Use the Power Rule for Logarithms to move the 2 in 2 log 3 x to the exponent of x = log 3 x 2y Use the Product Rule for Logarithms. The answer is 2log 3 x y Example 7 ...
