Introduction
Scientific notation is a powerful tool used in mathematics to express very large or very small numbers in a more manageable and concise form. It is a fundamental concept in mathematics, particularly in algebra, calculus, and physics. In this article, we will explore the concept of scientific notation and provide a step-by-step guide on how to match decimal numbers with their correct pairs.
What is Scientific Notation?
Scientific notation is a way of expressing numbers in the form of a product of a number between 1 and 10 and a power of 10. It is a shorthand method of writing very large or very small numbers. The general form of scientific notation is:
a × 10^n
where a is a number between 1 and 10, and n is an integer.
Examples of Scientific Notation
- 3.14 × 10^0 = 3.14
- 2.5 × 10^2 = 250
- 6.02 × 10^23 = 6,020,000,000,000,000,000
Matching Decimal Numbers with Correct Pairs
Now that we have a basic understanding of scientific notation, let's move on to the main topic of this article: matching decimal numbers with their correct pairs. We will use the following decimal numbers and their corresponding scientific notation pairs:
- 30,700 - $\square$ $3.07 \times 10^4$
- 0.000307 - $\square$ $3.07 \times 10^{-4}$
Step 1: Understanding the Decimal Numbers
Let's start by understanding the decimal numbers we are given. The first decimal number is 30,700, which is a large number. The second decimal number is 0.000307, which is a very small number.
Step 2: Understanding the Scientific Notation Pairs
Now, let's move on to the scientific notation pairs. The first pair is $3.07 \times 10^4$, which represents the number 30,700. The second pair is $3.07 \times 10^{-4}$, which represents the number 0.000307.
Step 3: Matching the Decimal Numbers with the Correct Pairs
Now that we have a basic understanding of the decimal numbers and the scientific notation pairs, let's move on to matching them. To match the decimal numbers with the correct pairs, we need to follow these steps:
- Take the decimal number and express it in scientific notation.
- Compare the scientific notation with the given pairs.
- Match the decimal number with the correct pair.
Step 4: Expressing the Decimal Numbers in Scientific Notation
Let's express the decimal numbers in scientific notation.
- 30,700 = 3.07 × 10^4
- 0.000307 = 3.07 × 10^{-4}
Step 5: Matching the Decimal Numbers with the Correct Pairs
Now that we have expressed the decimal numbers in scientific notation, let's match them with the correct pairs.
- 30,700 - $\square$ $3.07 \times 10^4$
- 0.000307 - $\square$ $3.07 \times 10^{-4}$
Conclusion
In this article, we have explored the concept of scientific notation and provided a step-by-step guide on how to match decimal numbers with their correct pairs. We have used the following decimal numbers and their corresponding scientific notation pairs:
- 30,700 - $\square$ $3.07 \times 10^4$
- 0.000307 - $\square$ $3.07 \times 10^{-4}$
We have expressed the decimal numbers in scientific notation and matched them with the correct pairs. We hope that this article has provided a clear understanding of scientific notation and how to match decimal numbers with their correct pairs.
