Solution

To simplify the given logarithmic expression step by step, we can use the properties of logarithms. The expression is:

12logbx+2logb610logby5logbz\frac{1}{2} \log_b x + 2 \log_b 6 - 10 \log_b y - 5 \log_b z

We will use the following properties of logarithms:

  1. alogbc=logb(ca)a \log_b c = \log_b (c^a)
  2. logbm+logbn=logb(mn)\log_b m + \log_b n = \log_b (mn)
  3. logbmlogbn=logb(mn)\log_b m - \log_b n = \log_b \left( \frac{m}{n} \right)

Step-by-Step Solution:

  1. Apply the power rule to each term:

12logbx=logbx12\frac{1}{2} \log_b x = \log_b x^{\frac{1}{2}}

2logb6=logb62=logb362 \log_b 6 = \log_b 6^2 = \log_b 36

10logby=logby1010 \log_b y = \log_b y^{10}

5logbz=logbz55 \log_b z = \log_b z^5

  1. Rewrite the expression using these transformations:

logbx12+logb36logby10logbz5\log_b x^{\frac{1}{2}} + \log_b 36 - \log_b y^{10} - \log_b z^5

  1. Combine the logarithms using the product and quotient rules:

First, combine the addition terms:

logbx12+logb36=logb(x1236)\log_b x^{\frac{1}{2}} + \log_b 36 = \log_b \left( x^{\frac{1}{2}} \cdot 36 \right)

Next, combine the subtraction terms:

logb(x1236)logby10=logb(x1236y10)\log_b \left( x^{\frac{1}{2}} \cdot 36 \right) - \log_b y^{10} = \log_b \left( \frac{x^{\frac{1}{2}} \cdot 36}{y^{10}} \right)

Then:

logb(x1236y10)logbz5=logb(x1236y10z5)\log_b \left( \frac{x^{\frac{1}{2}} \cdot 36}{y^{10}} \right) - \log_b z^5 = \log_b \left( \frac{x^{\frac{1}{2}} \cdot 36}{y^{10} \cdot z^5} \right)

  1. Simplify the expression:

logb(36xy10z5)\log_b \left( \frac{36 \sqrt{x}}{y^{10} z^5} \right)

So, the simplified form of the given expression is:

logb(36xy10z5)\log_b \left( \frac{36 \sqrt{x}}{y^{10} z^5} \right)
