Logarithm Properties and Applications

This video tutorial covers the properties of logarithms, including product, quotient, and power properties. It provides examples of how to apply these properties in calculations. The tutorial also explains how to expand and condense logarithmic expressions and introduces the change of base formula for using calculators. The lesson concludes with a summary of key points.

What is the relationship between logarithms and exponentials?

• They are unrelated.

• They are inverses of each other.

• They are the same.

• They are both linear functions.

What does the product property of logarithms state?

• log_b(M * N) = log_b(M) + log_b(N)

• log_b(M * N) = log_b(M) - log_b(N)

• log_b(M * N) = log_b(M) * log_b(N)

• log_b(M * N) = log_b(M) / log_b(N)

How does the quotient property of logarithms simplify log_b(M/N)?

• log_b(M) / log_b(N)

• log_b(M) + log_b(N)

• log_b(M) - log_b(N)

• log_b(M) * log_b(N)

What is the power property of logarithms?

• log_b(M^N) = log_b(M) / N

• log_b(M^N) = log_b(M) + N

• log_b(M^N) = log_b(M) - N

• log_b(M^N) = N * log_b(M)

In the example using the quotient property, what is log base 3 of 6?

• log base 3 of 12 * log base 3 of 2

• log base 3 of 12 / log base 3 of 2

• log base 3 of 12 - log base 3 of 2

• log base 3 of 12 + log base 3 of 2

How is log base 3 of 24 evaluated using the product property?

• log base 3 of 12 / log base 3 of 2

• log base 3 of 12 * log base 3 of 2

• log base 3 of 12 - log base 3 of 2

• log base 3 of 12 + log base 3 of 2

What is the result of log base 3 of 32 using the power property?

• log base 3 of 2 - 5

• 5 * log base 3 of 2

• log base 3 of 2^5

• log base 3 of 2 + 5

When expanding log base 7 of 3x^2 over 5y^3, what is the first step?

• Use the power property

• Use the quotient property

• Use the change of base formula

• Use the product property

What is the result of condensing Ln 8 + Ln 25 - Ln 10?

• Ln 8 * 25 / 10

• Ln 8 / 25 * 10

• Ln 8 + 25 - 10

• Ln 8 - 25 + 10

What is the change of base formula for log base C of A?

• log(A) / log(C)

• log(A) * log(C)

• log(C) / log(A)

• log(C) - log(A)
