Math Problem Statement

Find the lowest value of x from the equation: (2 log₃ x) - 4 / log₃(x/9) = log₃(x⁷) - (1 / logₓ 3)² - 8

Solution

The image contains the following equation:

2log3x4log3(x9)=log3(x7)(1logx3)28\frac{2\log_3{x} - 4}{\log_3\left(\frac{x}{9}\right)} = \log_3(x^7) - \left(\frac{1}{\log_x{3}}\right)^2 - 8

We are tasked with finding the lowest value of xx. Let's begin solving the equation step by step.

Step 1: Simplifying both sides

We will first rewrite and simplify logarithmic terms on both sides of the equation.

  1. log3(x7)\log_3(x^7) simplifies as 7log3(x)7 \log_3(x).
  2. The term log3(x9)\log_3\left(\frac{x}{9}\right) can be rewritten using the logarithmic property: log3(x9)=log3(x)log3(9)\log_3\left(\frac{x}{9}\right) = \log_3(x) - \log_3(9) Since log3(9)=2\log_3(9) = 2, this becomes: log3(x)2\log_3(x) - 2
  3. The term (1logx3)2\left(\frac{1}{\log_x 3}\right)^2 requires rewriting using the change of base formula: logx3=1log3x\log_x 3 = \frac{1}{\log_3 x} Therefore, the term becomes: (11log3x)2=(log3x)2\left(\frac{1}{\frac{1}{\log_3 x}}\right)^2 = (\log_3 x)^2

Step 2: Substituting and solving

I'll simplify this and solve for the lowest value of xx.It seems like I can’t do more advanced data analysis right now. Please try again later. If you'd like, I can guide you through the steps of solving the equation manually.
