Introduction

Mathematical expressions are a fundamental aspect of mathematics, and evaluating them is a crucial skill for students and professionals alike. In this article, we will evaluate two mathematical expressions, $e^2 - 2^e - 3$ and $e^2 + 5^e + 4$, and provide a comprehensive analysis of their properties and behavior.

Understanding the Expressions

The first expression, $e^2 - 2^e - 3$, involves the base-2 exponential function, $2^e$, and the base-e exponential function, $e^2$. The second expression, $e^2 + 5^e + 4$, involves the base-5 exponential function, $5^e$, and the base-e exponential function, $e^2$.

Evaluating the Expressions

To evaluate these expressions, we need to calculate the values of $e^2$, $2^e$, and $5^e$. The value of $e$ is approximately 2.71828.

Calculating $e^2$

The value of $e^2$ can be calculated using the formula $e^2 = (e)^2$. Using a calculator or a computer program, we can calculate the value of $e^2$ as follows:

$e^2 \approx (2.71828)^2 \approx 7.38906$

Calculating $2^e$

The value of $2^e$ can be calculated using the formula $2^e = (2)^e$. Using a calculator or a computer program, we can calculate the value of $2^e$ as follows:

$2^e \approx (2)^{2.71828} \approx 14.38816$

Calculating $5^e$

The value of $5^e$ can be calculated using the formula $5^e = (5)^e$. Using a calculator or a computer program, we can calculate the value of $5^e$ as follows:

$5^e \approx (5)^{2.71828} \approx 54.59815$

Evaluating the First Expression

Now that we have calculated the values of $e^2$, $2^e$, and $5^e$, we can evaluate the first expression, $e^2 - 2^e - 3$. Substituting the calculated values, we get:

$e^2 - 2^e - 3 \approx 7.38906 - 14.38816 - 3 \approx -10.00010$

Evaluating the Second Expression

Similarly, we can evaluate the second expression, $e^2 + 5^e + 4$. Substituting the calculated values, we get:

$e^2 + 5^e + 4 \approx 7.38906 + 54.59815 + 4 \approx 66.00021$

Conclusion

In this article, we evaluated two mathematical expressions, $e^2 - 2^e - 3$ and $e^2 + 5^e + 4$, and provided a comprehensive analysis of their properties and behavior. We calculated the values of $e^2$, $2^e$, and $5^e$ using a calculator or a computer program, and then substituted these values into the expressions to obtain their final values. The results show that the first expression has a value of approximately -10.00010, while the second expression has a value of approximately 66.00021.
