Introduction

In mathematics, expressing numbers in expanded form is a fundamental concept that helps us understand the value and structure of numbers. It involves breaking down a number into its individual digits and representing each digit as a product of a coefficient and a power of 10. In this article, we will explore the concept of expressing numbers in expanded form using powers of 10, and we will use the number 13762 as an example.

What is Expanded Form?

Expanded form is a way of representing a number as a sum of its individual digits, each multiplied by a power of 10. For example, the number 1234 can be expressed in expanded form as:

${ 1234 = (1 \times 10^3) + (2 \times 10^2) + (3 \times 10^1) + (4 \times 10^0) }$

Expressing 13762 in Expanded Form

Now, let's apply the concept of expanded form to the number 13762. We can break down this number into its individual digits and represent each digit as a product of a coefficient and a power of 10.

${ 13762 = (1 \times 10^4) + (3 \times 10^3) + (7 \times 10^2) + (6 \times 10^1) + (2 \times 10^0) }$

Understanding the Powers of 10

In the expanded form of 13762, we see that each digit is multiplied by a power of 10. The powers of 10 are:

${ 10^4 }$ (10,000)
${ 10^3 }$ (1,000)
${ 10^2 }$ (100)
${ 10^1 }$ (10)
${ 10^0 }$ (1)

Why Do We Use Powers of 10?

We use powers of 10 because they provide a convenient way to represent large numbers in a compact form. By multiplying each digit by a power of 10, we can easily read and write large numbers without having to write out all the zeros.

Real-World Applications

Expressing numbers in expanded form has many real-world applications. For example, in finance, accountants use expanded form to represent large numbers in financial statements. In science, researchers use expanded form to represent large numbers in scientific notation.

Conclusion

In conclusion, expressing numbers in expanded form using powers of 10 is a fundamental concept in mathematics that helps us understand the value and structure of numbers. By breaking down a number into its individual digits and representing each digit as a product of a coefficient and a power of 10, we can easily read and write large numbers. The concept of expanded form has many real-world applications, and it is an essential tool for anyone who works with numbers.

Additional Examples

Here are a few more examples of numbers expressed in expanded form using powers of 10:

4567 = (4 × 10^3) + (5 × 10^2) + (6 × 10^1) + (7 × 10^0)
9821 = (9 × 10^3) + (8 × 10^2) + (2 × 10^1) + (1 × 10^0)
13579 = (1 × 10^4) + (3 × 10^3) + (5 × 10^2) + (7 × 10^1) + (9 × 10^0)

Practice Problems
