Standardizing Formula Simplification for Technical Training

As a technical documentation specialist for a software company, you are writing a training guide for a new automated calculation engine. You need to provide a clear, step-by-step explanation of the logic used to simplify the expression (y9y4)2\left(\frac{y^9}{y^4}\right)^2. In your essay, describe the process by recalling and stating:

  1. Which mathematical property must be applied first to the terms inside the parentheses and how the exponents are manipulated in that step.
  2. The intermediate expression that results from this first simplification.
  3. Which mathematical property is applied next to the intermediate expression to reach the final simplified form.
  4. Why the standard order of operations requires the fraction inside the parentheses to be simplified before applying the outer exponent.
