Introduction

Exponential equations are a fundamental concept in mathematics, and solving them requires a clear understanding of the underlying principles. In this article, we will focus on solving a specific exponential equation: $5^2 x^0 y^3 = ?$. We will break down the solution into manageable steps, making it easy to follow and understand.

Understanding Exponential Notation

Before we dive into solving the equation, let's take a moment to understand the notation used. Exponential notation is a shorthand way of writing repeated multiplication. For example, $5^2$ means $5 \times 5$, and $x^0$ means $x$ multiplied by itself zero times, which is equal to 1.

Breaking Down the Equation

Now that we have a basic understanding of exponential notation, let's break down the given equation: $5^2 x^0 y^3 = ?$. We can see that the equation consists of three terms:

1. $5^2$
2. $x^0$
3. $y^3$

Solving the First Term: $5^2$

The first term is $5^2$, which means $5 \times 5$. To solve this, we simply multiply 5 by itself:

$5^2 = 5 \times 5 = 25$

Solving the Second Term: $x^0$

The second term is $x^0$, which means $x$ multiplied by itself zero times. As we mentioned earlier, any number raised to the power of 0 is equal to 1. Therefore, $x^0 = 1$.

Solving the Third Term: $y^3$

The third term is $y^3$, which means $y$ multiplied by itself three times. To solve this, we need to multiply $y$ by itself three times:

$y^3 = y \times y \times y = y^3$

However, we can simplify this further by recognizing that $y^3$ is equal to $y \times y^2$. Therefore, we can rewrite the equation as:

$5^2 x^0 y^3 = 25 \times 1 \times y^3 = 25y^3$

Combining the Terms

Now that we have solved each term individually, we can combine them to get the final solution:

$5^2 x^0 y^3 = 25y^3$

Conclusion

In this article, we solved the exponential equation $5^2 x^0 y^3 = ?$ by breaking it down into manageable steps. We started by understanding the notation used, then solved each term individually, and finally combined them to get the final solution. We hope this article has provided a clear and concise guide to solving exponential equations.
