Q. Is −4-4 an irrational number?\newlineChoices:\newline(A) yes\newline(B) no
  1. Define irrational numbers: Step 11: Define irrational numbers.\newlineIrrational numbers are numbers that cannot be expressed as a fraction of two integers, where the denominator is not zero. They have non-terminating, non-repeating decimal expansions.
  2. Analyze number −4-4: Step 22: Analyze the number −4-4.\newline−4-4 is an integer, which means it can be expressed as −41-\frac{4}{1}, where −4-4 is the numerator and 11 is the denominator.
  3. Determine if −4-4 is irrational: Step 33: Determine if −4-4 is irrational.\newlineSince −4-4 can be expressed as a fraction of two integers (as shown in Step 22), it is not an irrational number. It does not have a non-terminating, non-repeating decimal expansion; it's just −4.0-4.0 when written as a decimal.
