===========================================================

Introduction

---

In mathematics, the concept of an inverse is a fundamental idea that plays a crucial role in various branches of mathematics, including algebra, geometry, and calculus. The inverse of a number is a value that, when multiplied by the original number, results in a product of 1. In this article, we will delve into the concept of the sum of a number and its inverse, and explore how it relates to the given equation: $\frac{39}{52}$.

What is an Inverse?

---

An inverse of a number is a value that, when multiplied by the original number, results in a product of 1. For example, the inverse of 2 is $\frac{1}{2}$, because $2 \times \frac{1}{2} = 1$. Similarly, the inverse of 3 is $\frac{1}{3}$, because $3 \times \frac{1}{3} = 1$.

The Sum of a Number and Its Inverse

---

The sum of a number and its inverse is a mathematical expression that involves adding a number to its inverse. For example, the sum of 2 and its inverse $\frac{1}{2}$ is $2 + \frac{1}{2}$. Similarly, the sum of 3 and its inverse $\frac{1}{3}$ is $3 + \frac{1}{3}$.

The Given Equation

---

The given equation is $\frac{39}{52}$. This equation represents the sum of a number and its inverse. To find the number and its inverse, we need to analyze the equation and identify the values that satisfy it.

Solving the Equation

---

To solve the equation, we can start by assuming that the number is $x$. Then, the inverse of $x$ is $\frac{1}{x}$. The sum of $x$ and its inverse is $x + \frac{1}{x}$. We are given that this sum is equal to $\frac{39}{52}$.

Algebraic Manipulation

---

We can start by multiplying both sides of the equation by $x$ to eliminate the fraction. This gives us:

$x^2 + 1 = \frac{39}{52}x$

Rearranging the Equation

---

We can rearrange the equation to get:

$x^2 - \frac{39}{52}x + 1 = 0$

Solving the Quadratic Equation

---

This is a quadratic equation in $x$. We can solve it using the quadratic formula:

$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$

Substituting Values

---

In this case, $a = 1$, $b = -\frac{39}{52}$, and $c = 1$. Substituting these values into the quadratic formula, we get:

$x = \frac{\frac{39}{52} \pm \sqrt{\left(-\frac{39}{52}\right)^2 - 4(1)(1)}}{2(1)}$

Simplifying the Expression

---

Simplifying the expression, we get:

$x = \frac{\frac{39}{52} \pm \sqrt{\frac{1521}{2704} - 4}}{2}$

Further Simplification

---

Further simplifying the expression, we get:

$x = \frac{\frac{39}{52} \pm \sqrt{\frac{1521 - 10736}{2704}}}{2}$

Final Simplification

---

Finally, simplifying the expression, we get:

$x = \frac{\frac{39}{52} \pm \sqrt{\frac{-9215}{2704}}}{2}$

Conclusion

---

The sum of a number and its inverse is a mathematical expression that involves adding a number to its inverse. The given equation $\frac{39}{52}$ represents the sum of a number and its inverse. By solving the quadratic equation, we found that the number is $x = \frac{\frac{39}{52} \pm \sqrt{\frac{-9215}{2704}}}{2}$. This is a complex number, which means that the number and its inverse are not real numbers.

Real-World Applications
