Introduction

---

In mathematics, a new operation is defined as $x * y = \log_x y$. This operation combines two numbers, $x$ and $y$, to produce a result that is the logarithm of $y$ with base $x$. In this article, we will evaluate this operation and explore its properties.

Definition and Properties

---

The operation $x * y = \log_x y$ is defined as the logarithm of $y$ with base $x$. This means that for any positive real numbers $x$ and $y$, the result of the operation is the exponent to which $x$ must be raised to produce $y$.

Commutativity

---

One of the fundamental properties of an operation is commutativity, which states that the order of the operands does not affect the result. In the case of the operation $x * y = \log_x y$, we can see that the order of $x$ and $y$ does not matter.

• $\log_x y = \log_y x$

This is because the logarithm function is symmetric, and the base and the argument can be swapped without changing the result.

Associativity

---

Another important property of an operation is associativity, which states that the order in which the operation is applied to three or more operands does not affect the result. In the case of the operation $x * y = \log_x y$, we can see that the order in which the operation is applied does not matter.

• $(x * y) * z = x * (y * z)$

This is because the logarithm function is associative, and the order in which the operation is applied does not affect the result.

Distributivity

---

The operation $x * y = \log_x y$ is also distributive over addition. This means that the operation can be applied to the sum of two numbers, and the result is the same as if the operation had been applied to each number separately.

• $x * (y + z) = x * y + x * z$

This is because the logarithm function is distributive over addition, and the operation can be applied to the sum of two numbers without changing the result.

Evaluation

---

Now that we have explored the properties of the operation $x * y = \log_x y$, let's evaluate it for some specific values of $x$ and $y$.

Example 1

---

Suppose we want to evaluate the operation $x * y = \log_x y$ for $x = 2$ and $y = 4$. We can see that:

• $\log_2 4 = 2$

This is because $2^2 = 4$, so the logarithm of $4$ with base $2$ is $2$.

Example 2

---

Suppose we want to evaluate the operation $x * y = \log_x y$ for $x = 3$ and $y = 9$. We can see that:

• $\log_3 9 = 2$

This is because $3^2 = 9$, so the logarithm of $9$ with base $3$ is $2$.

Example 3

---

Suppose we want to evaluate the operation $x * y = \log_x y$ for $x = 4$ and $y = 16$. We can see that:

• $\log_4 16 = 2$

This is because $4^2 = 16$, so the logarithm of $16$ with base $4$ is $2$.

Conclusion

---

In conclusion, the operation $x * y = \log_x y$ is a well-defined and interesting mathematical operation. It has several properties, including commutativity, associativity, and distributivity over addition. We have also evaluated the operation for some specific values of $x$ and $y$, and seen that it produces the expected results.

Future Work

---

There are several directions in which this research could be extended. One possibility is to explore the properties of the operation $x * y = \log_x y$ in more detail, and to investigate its behavior for different values of $x$ and $y$. Another possibility is to consider the operation $x * y = \log_x y$ in the context of other mathematical structures, such as groups or rings.
