Professional Training: Simplifying Radical Measurements

You are a senior technical assistant at an engineering firm, and you are training a new intern on how to simplify blueprint measurements. One of the measurements is expressed as (42)(4+2)(4 - \sqrt{2})(4 + \sqrt{2}). To help the intern understand the shortcut for this calculation, write a brief explanation describing how to apply the 'Product of Conjugates Pattern.' In your response, you must:

  1. State the algebraic formula used for the Product of Conjugates Pattern.
  2. Identify the numerical values for 'aa' and 'bb' in the expression (42)(4+2)(4 - \sqrt{2})(4 + \sqrt{2}).
  3. Show the steps for calculating the squares of both the first and last terms.
  4. Provide the final simplified integer result.
  5. Explain why the square root symbol is no longer present in the final result based on the properties of squaring a radical.
