Introduction

In the realm of mathematics, a logical statement is a sentence that can be classified as either true or false. It is a fundamental concept in logic and mathematics, and it plays a crucial role in various mathematical disciplines, including algebra, geometry, and number theory. In this article, we will examine the given sentence and determine whether it is a logical statement or not.

What is a Logical Statement?

A logical statement is a sentence that can be evaluated as true or false. It is a statement that can be verified or falsified through mathematical reasoning and evidence. For example, the sentence "2 + 2 = 4" is a logical statement because it can be verified as true through mathematical operations. On the other hand, the sentence "2 + 2 = 5" is not a logical statement because it is false and cannot be verified through mathematical operations.

The Given Sentence

The given sentence is: "1024 is the smallest 4-digit number that is a perfect square."

Analysis

To determine whether this sentence is a logical statement, we need to analyze its components. The sentence consists of two main parts: the number 1024 and the claim that it is the smallest 4-digit number that is a perfect square.

Perfect Square

A perfect square is a number that can be expressed as the square of an integer. For example, 16 is a perfect square because it can be expressed as 4^2. Similarly, 1024 is a perfect square because it can be expressed as 32^2.

Smallest 4-Digit Number

A 4-digit number is a number that has four digits. The smallest 4-digit number is 1000.

Is 1024 the Smallest 4-Digit Number that is a Perfect Square?

To determine whether 1024 is the smallest 4-digit number that is a perfect square, we need to examine the perfect squares between 1000 and 1024. The perfect squares between 1000 and 1024 are:

30^2 = 900 (less than 1000)
31^2 = 961 (less than 1024)
32^2 = 1024 (equal to 1024)

As we can see, 1024 is indeed the smallest 4-digit number that is a perfect square.

Conclusion

Based on our analysis, we can conclude that the sentence "1024 is the smallest 4-digit number that is a perfect square" is a logical statement. It can be verified as true through mathematical operations and evidence. Therefore, the correct answer is:

A. Statement

Why is this sentence a logical statement?

This sentence is a logical statement because it can be evaluated as true or false through mathematical reasoning and evidence. We can verify that 1024 is indeed the smallest 4-digit number that is a perfect square by examining the perfect squares between 1000 and 1024. This sentence is a clear example of a logical statement in mathematics.

What are the implications of this sentence being a logical statement?

The implications of this sentence being a logical statement are significant. It means that we can use mathematical reasoning and evidence to verify or falsify this sentence. This sentence is a fundamental concept in number theory, and it has important implications for various mathematical disciplines, including algebra and geometry.

Real-World Applications

The concept of perfect squares and the smallest 4-digit number that is a perfect square has real-world applications in various fields, including:

Computer Science: Perfect squares are used in computer science to optimize algorithms and data structures.
Engineering: Perfect squares are used in engineering to design and optimize systems and structures.
Finance: Perfect squares are used in finance to calculate interest rates and investment returns.
