Logarithmic Properties and Exponents

The video tutorial explains how to expand logarithms using properties of logarithms. It covers the conversion of square roots to exponent form and demonstrates the expansion of logarithms involving products and quotients. The tutorial provides two examples: one using common logarithms and another using natural logarithms, highlighting the application of the power property of logarithms to simplify expressions.

What is the exponent form of a square root?

• X to the power of 1

• X to the power of 1/2

• X to the power of 3

• X to the power of 2

How can you express the logarithm of a quotient?

• As a division of two logarithms

• As a difference of two logarithms

• As a product of two logarithms

• As a sum of two logarithms

What is the result of applying the power property to log(X^1/2)?

• log X^2

• 2 log X

• 1/2 log X

• log X

What is the expanded form of log(X^1/2 * Y^1/2 / Z^1/2)?

• log X + log Y - log Z

• log X - log Y + log Z

• 1/2 log X - 1/2 log Y + 1/2 log Z

• 1/2 log X + 1/2 log Y - 1/2 log Z

What property allows moving exponents to the front of a logarithm?

• Root property

• Product property

• Quotient property

• Power property

In the natural logarithm example, what is the first step?

• Rewrite as a sum of logs

• Rewrite as a natural log of X to the power of 1/2

• Rewrite as a difference of logs

• Rewrite as a product of logs

In the natural logarithm example, what is the denominator?

• X divided by four

• X times three

• X plus four

• X minus three

Why can't the logarithm of a quotient be expanded into a sum?

• Because it requires a division to expand into a sum

• Because it requires a difference to expand into a sum

• Because it requires a product to expand into a sum

• Because it is already in its simplest form

What is the expanded form of ln(X^1/2 * (X-3)^1/2)?

• 1/2 ln X - 1/2 ln (X-3)

• ln X - ln (X-3)

• 1/2 ln X + 1/2 ln (X-3)

• ln X + ln (X-3)

What is the limitation of expanding logarithms into sums and differences?

• It can only be done with products and quotients

• It can only be done with sums and differences

• It can only be done with divisions and multiplications

• It can only be done with powers and roots
