To determine which of the numbers are irrational, we first need to understand what irrational numbers are. An irrational number is a real number that cannot be expressed as a simple fraction (i.e., a/b where a and b are integers and b is not zero). Irrational numbers have non-repeating, non-terminating decimal representations.
Let's analyze the numbers you've provided:
1. **-1**: This is a rational number because it can be expressed as -1/1.
2. **1/4**: This is a rational number because it is a fraction.
3. **2**: This is a rational number because it can be expressed as 2/1.
4. **2/4**: This simplifies to 1/2, which is also a rational number.
5. **TT**: This seems to be a typographical error. If this is intended to represent a number like π or another symbol, please clarify. But as it stands, it's not a number.
6. **10/3**: This is a rational number because it is a fraction.
**Conclusion**: None of the numbers listed (assuming TT is not a recognizable number) are irrational. All are rational numbers.

The square root of 1, written as \(\sqrt{1}\), is not an irrational number.
In fact:
\[
\sqrt{1} = 1
\]
Since 1 can be expressed as the fraction \(1/1\), it is a rational number. Therefore, \(\sqrt{1}\) is a rational number, not an irrational one.

Natural numbers are the set of positive integers starting from 1 and going upwards (1, 2, 3, 4, ...). They do not include negative numbers, fractions, or decimals.
Let's look at the numbers you provided:
1. **9.94**: This is not a natural number because it is a decimal (not a whole number).
2. **5**: This is a natural number because it is a positive integer.
3. **TT**: This does not represent a number. If it's a typographical error or something specific, please clarify, but as it stands, it is not a natural number.
4. **-5**: This is not a natural number because it is negative.
**Conclusion**: The only natural number among the options given is **5**.

Let's analyze the numbers you've provided to determine which of them are natural numbers.
1. **13/16**: This is a fraction and not a whole number, so it is not a natural number.
2. **TT**: As before, this does not represent a specific numerical value. If you meant something else, please clarify. As it stands, it is not a natural number.
3. **\(\sqrt{4}\)**: The square root of 4 is 2, which is a whole number. Therefore, \( \sqrt{4} \) is a natural number.
4. **35.494**: This is a decimal number and not a whole number. Therefore, it is not a natural number.
**Conclusion**: The only natural number among the options given is **\(\sqrt{4} (which equals 2)\)**.

Real numbers include all the numbers on the number line, encompassing natural numbers, whole numbers, integers, rational numbers, and irrational numbers. Let's assess each of the provided numbers:
1. **-57**: This is a real number. It is an integer and also a rational number.
2. **\(\sqrt{20}\)**: This is a real number. While it is an irrational number (since it cannot be simplified to a fraction of integers), it still belongs to the set of real numbers.
3. **\(\sqrt{64}\)**: This is a real number as well. It equals 8, which is an integer and thus a rational number.
4. **\(\sqrt{0}\)**: This is equal to 0, which is also a real number. Zero is considered an integer and a rational number.
**Conclusion**: All the numbers listed (-57, \(\sqrt{20}\), \(\sqrt{64}\), and \(\sqrt{0}\)) are real numbers.
1. **-57**: This is a real number. It is an integer and also a rational number.
