Logarithms. The mathematics of logarithms and exponentials occurs naturally in many branches of science. It is very important in solving problems related to growth and decay. The growth and decay may be that of a plant or a population, a crystalline structure or money in the bank.
Exponent and Logarithm Practice Problems for Precalculus and Calculus. 1. Expand (x + y)5. 2. Simplify the following expression: 3. Evaluate the following powers: 130 = , ( 8)2/3 =. −. 4.
Unit Overview. In this unit you will evaluate natural exponential and natural logarithmic functions and model exponential growth and decay processes. You will also solve logarithmic and exponential equations by using algebra and graphs.
EXPONENT RULES & PRACTICE. PRODUCT RULE: To multiply when two bases are the same, write the base and ADD the exponents. 2. QUOTIENT RULE: To divide when two bases are the same, write the base and SUBTRACT the exponents. 3. ZERO EXPONENT RULE: Any base (except 0) raised to the zero power is equal to one. 4.
