Solving Exponential Capacity Models

A logistics company is modeling its supply chain expansion, and an analyst determines that the number of warehouse hubs, xx, needed over the next decade can be modeled by the exponential equation 7x=43{}7^x = 43. To verify the model's timeline, you must solve this equation for xx.

In your role as a junior operations analyst, write a brief explanation of the step-by-step mathematical process to solve 7x=43{}7^x = 43 using common logarithms. Your explanation must recall and address the following:

  1. What equation do you get immediately after taking the common logarithm of both sides of ${}7^x = 43$?
  2. What specific algebraic property of logarithms allows you to rewrite the left side of that equation so that the variable xx is no longer in the exponent? State the name of this property.
  3. What is the equation after applying that property?
  4. How do you isolate xx to find the exact solution, and what is the final exact expression for xx as a fraction of logarithms?
