Write $4.635 \times 10^4$ As An Ordinary Number.
Scientific notation is a way of expressing very large or very small numbers in a more manageable form. It consists of a number between 1 and 10 multiplied by a power of 10. In this article, we will learn how to convert scientific notation to ordinary numbers.
Understanding Scientific Notation
Scientific notation is a shorthand way of expressing numbers that are too large or too small to be written in standard decimal form. It consists of two parts: a coefficient and a power of 10. The coefficient is a number between 1 and 10, and the power of 10 is an exponent that indicates the number of places to move the decimal point.
For example, the number 4.635 × 10^4 can be written in scientific notation as 4.635 × 10^4. The coefficient is 4.635, and the power of 10 is 4. This means that the decimal point in 4.635 should be moved 4 places to the right to get the ordinary number.
Converting Scientific Notation to Ordinary Numbers
To convert scientific notation to an ordinary number, we need to move the decimal point in the coefficient by the number of places indicated by the power of 10. If the power of 10 is positive, we move the decimal point to the right. If the power of 10 is negative, we move the decimal point to the left.
Let's convert the number 4.635 × 10^4 to an ordinary number. Since the power of 10 is 4, we need to move the decimal point in 4.635 4 places to the right.
4.635 × 10^4 = 46,350
Therefore, the ordinary number equivalent of 4.635 × 10^4 is 46,350.
Examples of Converting Scientific Notation to Ordinary Numbers
Here are a few more examples of converting scientific notation to ordinary numbers:
- 2.75 × 10^3 = 2,750
- 9.25 × 10^2 = 925
- 6.8 × 10^1 = 68
- 3.45 × 10^0 = 3.45
- 2.1 × 10^-1 = 0.21
- 8.9 × 10^-2 = 0.089
Tips for Converting Scientific Notation to Ordinary Numbers
Here are a few tips to keep in mind when converting scientific notation to ordinary numbers:
- Make sure to move the decimal point by the correct number of places.
- If the power of 10 is positive, move the decimal point to the right. If the power of 10 is negative, move the decimal point to the left.
- Use a calculator or a computer to help you with the conversion if you are unsure.
Conclusion
Converting scientific notation to ordinary numbers can be a bit tricky, especially for those who are new to the concept. In this article, we will answer some of the most frequently asked questions about converting scientific notation to ordinary numbers.
Q: What is scientific notation?
A: Scientific notation is a way of expressing very large or very small numbers in a more manageable form. It consists of a number between 1 and 10 multiplied by a power of 10.
Q: How do I convert scientific notation to an ordinary number?
A: To convert scientific notation to an ordinary number, you need to move the decimal point in the coefficient by the number of places indicated by the power of 10. If the power of 10 is positive, move the decimal point to the right. If the power of 10 is negative, move the decimal point to the left.
Q: What if the power of 10 is a negative number?
A: If the power of 10 is a negative number, you need to move the decimal point to the left. For example, if you have 4.635 × 10^-2, you would move the decimal point 2 places to the left to get 0.4635.
Q: What if the power of 10 is a positive number?
