1 answer

To find the product of \( 5 - \sqrt{5} \) and \( \frac{1}{6} \), let's start with the first term.

  1. Calculate \( 5 - \sqrt{5} \):

    • This expression combines a rational number (5) and an irrational number (\( \sqrt{5} \)), which means \( 5 - \sqrt{5} \) is an irrational number.
  2. Now we multiply it by \( \frac{1}{6} \):

    • The product is given by \( \left( 5 - \sqrt{5} \right) \left( \frac{1}{6} \right) = \frac{5 - \sqrt{5}}{6} \).
  3. This product is still irrational because it is a non-zero rational number divided by an irrational number. The result will always be irrational if the numerator is irrational.

Putting these calculations together, the product \( \frac{5 - \sqrt{5}}{6} \) is an irrational number.

So the correct response is:

0.3726 . . . ; an irrational number
