Math Problem Statement

Provide the correct property that justifies the expansion of the logarithm \(\log_b \frac{nx}{(y - m)^p}\).

Solution

To expand the logarithmic expression and provide the correct properties, let's go through each step:

Given Expression

logbnx(ym)p\log_b \frac{nx}{(y - m)^p}

Step 1

Using the Quotient Rule of logarithms, which states that logbAB=logbAlogbB\log_b \frac{A}{B} = \log_b A - \log_b B, we can separate the numerator and the denominator:

logbnx(ym)p=logb(nx)logb((ym)p)\log_b \frac{nx}{(y - m)^p} = \log_b (nx) - \log_b \left((y - m)^p\right)

So, the first blank should be filled with Quotient Rule.

Step 2

Now, apply the Product Rule of logarithms, which states that logb(AB)=logbA+logbB\log_b (A \cdot B) = \log_b A + \log_b B, to the term logb(nx)\log_b (nx):

logb(nx)logb((ym)p)=logb(n)+logb(x)logb((ym)p)\log_b (nx) - \log_b \left((y - m)^p\right) = \log_b (n) + \log_b (x) - \log_b \left((y - m)^p\right)

So, the second blank should be filled with Product Rule.

Step 3

Finally, apply the Power Rule of logarithms, which states that logb(Ac)=clogbA\log_b (A^c) = c \cdot \log_b A, to logb((ym)p)\log_b \left((y - m)^p\right):

logb(n)+logb(x)plogb(ym)\log_b (n) + \log_b (x) - p \cdot \log_b (y - m)

So, the third blank should be filled with Power Rule.

Final Answer

  • First blank: Quotient Rule
  • Second blank: Product Rule
  • Third blank: Power Rule
