Precalculus Chapter 5 Test Answers
In precalculus, Chapter 5 covers a variety of mathematical concepts, including logarithms, exponentials, and their properties. The chapter culminates with a test to assess students’ understanding of these topics. In this article, we will discuss the answers to the Precalculus Chapter 5 test, providing explanations for each question and solution.
Question 1:
Simplify the logarithmic expression log(base 3) 9^2 + log(base 3) 3^4.
To simplify this logarithmic expression, we can use the product rule of logarithms. According to the product rule, the sum of the logarithms of two numbers is equal to the logarithm of their product. Applying this rule, we can rewrite the expression as log(base 3) (9^2 * 3^4). Simplifying further, we get log(base 3) (81 * 81), which can be evaluated as log(base 3) 6561. Therefore, the answer to Question 1 is 6561.
Question 2:
Solve the exponential equation 2^x = 16.
To solve this exponential equation, we need to express both sides of the equation with the same base. In this case, we can rewrite 16 as 2^4. Therefore, the equation can be rewritten as 2^x = 2^4. By comparing the exponents, we can conclude that x equals 4. Hence, the solution to Question 2 is x = 4.
In conclusion, the Precalculus Chapter 5 test covers various topics related to logarithms and exponentials. By understanding the properties and rules associated with these mathematical concepts, students can successfully solve the given problems and determine the correct answers.
