To determine which of the options is a rational number, we need to understand what a rational number is. A rational number is any number that can be expressed as the quotient or fraction of two integers, where the denominator is not zero.
Let's check each of the options:
1. 88√: This is not a rational number because it includes the square root of a non-perfect square (88).
2. 8: This is a rational number because it can be expressed as the fraction 8/1, where the numerator and denominator are both integers.
3. 8: This is also a rational number because, like the previous option, it can be expressed as the fraction 8/1.
4. The fraction with numerator 8 and denominator square root of 8: This is not a rational number because it includes the square root of a non-perfect square (8). To confirm, we need to simplify the fraction. The square root of 8 can be simplified to 2√2, so the fraction becomes 8 / 2√2. However, this is not a rational number because it includes a square root.
5. 7–√: This is not a rational number because it includes the square root of a non-perfect square (7).
6. Square root of 7: Same as above, this is not a rational number because it involves the square root of a non-perfect square.
7. π (pi): This is not a rational number because it is an irrational number, which means it cannot be expressed as a fraction of two integers.
8. 7.8: This is a rational number because it can be expressed as the fraction 78/10, where both the numerator and denominator are integers.
Therefore, the rational numbers from the given options are 8 and 7.8.
