What is the smallest subset into which the following number fits?

square root of, 37, end square root
37

1 answer

To determine the smallest subset into which \(\sqrt{37}\) fits, we first need to recognize the type of number \(\sqrt{37}\) is.

  1. Natural Numbers (\(\mathbb{N}\)): These are the positive integers (1, 2, 3, ...). \(\sqrt{37}\) is not a natural number.

  2. Whole Numbers (\(\mathbb{W}\)): These include all natural numbers and zero (0, 1, 2, 3, ...). \(\sqrt{37}\) is not a whole number.

  3. Integers (\(\mathbb{Z}\)): This set includes positive integers, negative integers, and zero (..., -2, -1, 0, 1, 2, ...). \(\sqrt{37}\) is not an integer.

  4. Rational Numbers (\(\mathbb{Q}\)): A rational number is defined as the ratio of two integers (where the denominator is not zero). \(\sqrt{37}\) is an irrational number because it cannot be expressed as a fraction of two integers.

  5. Irrational Numbers: This subset includes numbers that cannot be expressed as a fraction. Since \(\sqrt{37}\) does not fit into any of the previous sets, it is an irrational number.

  6. Real Numbers (\(\mathbb{R}\)): This set includes all rational and irrational numbers. \(\sqrt{37}\) is a real number.

Thus, the smallest subset that \(\sqrt{37}\) fits into is the set of irrational numbers.
