The symbol \( V30 \) seems to refer to either a variable or an expression, but it isn't clear what it signifies without additional context.
If you are referring to \( \sqrt{30} \) or some other mathematical expression that includes the number 30 or the radical, then we can analyze it as follows:
1. **Rational Numbers**: A number is rational if it can be expressed as a fraction of two integers \( \frac{a}{b} \) where \( b \neq 0 \).
2. **Understanding \( \sqrt{30} \)**: The square root of 30 is not a perfect square, and it cannot be simplified into a fraction of two integers. Therefore, it is an *irrational number*.
If \( V30 \) is something different, please provide more details, and I can give a specific answer!

The notation \( V30 \) is not standard in mathematics and can refer to various things depending on the context. However, if we interpret it as the expression \( \sqrt{30} \) (which could be what you mean), then we can determine whether it is rational.
### Determining if \( \sqrt{30} \) is Rational
A number is rational if it can be expressed as a fraction of two integers \(\frac{a}{b}\) where \( b \neq 0 \). The square root of 30, denoted as \( \sqrt{30} \), is not a perfect square, meaning it cannot be expressed as an exact integer.
In fact, \( \sqrt{30} \) is approximately \( 5.477 \), and this value cannot be expressed as a fraction of two integers. Therefore, \( \sqrt{30} \) is an **irrational number**.
So, if by \( V30 \) you meant \( \sqrt{30} \), then \( V30 \) is **not a rational number**. If \( V30 \) refers to something else, please clarify!

The number \( \frac{4}{7} \) is a rational number.
### Explanation:
- **Rational Numbers**: A number is considered rational if it can be expressed as the fraction \( \frac{a}{b} \), where \( a \) and \( b \) are integers, and \( b \neq 0 \).
- In this case:
- \( a = 4 \) (an integer)
- \( b = 7 \) (an integer and not zero)
Since \( \frac{4}{7} \) fits this definition, it is indeed a rational number.

To determine if \( \frac{21}{V4} \) is a rational number, we first interpret \( V4 \) as \( \sqrt{4} \).
### Step 1: Evaluate \( V4 \)
- \( V4 = \sqrt{4} = 2 \)
### Step 2: Substitute into the Expression
Now we can rewrite the expression:
\[
\frac{21}{V4} = \frac{21}{\sqrt{4}} = \frac{21}{2}
\]
### Step 3: Determine if \( \frac{21}{2} \) is Rational
The fraction \( \frac{21}{2} \) can be expressed as two integers (21 and 2), where the denominator is not zero.
Since it meets the criteria for being a rational number, **yes**, \( \frac{21}{V4} \) is a rational number, and specifically, it equals \( 10.5 \) or \( 10 \frac{1}{2} \) when expressed as a decimal or mixed number.
### Step 1: Evaluate \( V4 \)
- \( V4 = \sqrt{4} = 2 \)
### Step 2: Substitute into the Expression
Now we can rewrite the expression:
\[
\frac{21}{V4} = \frac{21}{\sqrt{4}} = \frac{21}{2}
\]
### Step 3: Determine if \( \frac{21}{2} \) is Rational
The fraction \( \frac{21}{2} \) can be expressed as two integers (21 and 2), where the denominator is not zero.

The term "pie" appears to be a typographical error, and you might be referring to "pi" (π), which is a mathematical constant.
### Pi (π)
Pi (π) is defined as the ratio of the circumference of a circle to its diameter and is approximately equal to 3.14159.
### Is Pi (π) a Rational Number?
- **Rational Number**: A number is rational if it can be expressed as a fraction of two integers, \( \frac{a}{b} \), where \( b \neq 0 \).
- Pi (π) cannot be expressed as a fraction of two integers. It is a non-repeating, non-terminating decimal.
Therefore, **pi (π) is an irrational number**.
If you meant something different by "pie," please clarify!
