Adding Scientific Notation: (2x10^3) + (5x10^5)
This article will explore the process of adding two numbers in scientific notation: (2 x 10^3) + (5 x 10^5).
Understanding Scientific Notation
Scientific notation is a way to express very large or very small numbers in a compact form. It consists of two parts:
- A coefficient: A number between 1 and 10.
- A power of 10: Indicates the magnitude of the number.
For example, 5 x 10^5 represents 5 multiplied by 10 raised to the power of 5, which is equal to 500,000.
Adding Numbers in Scientific Notation
To add numbers in scientific notation, the following steps are necessary:
- Ensure the powers of 10 are the same. If they are not, adjust one of the numbers to match the other.
- Add the coefficients.
- Keep the power of 10 the same.
Example: (2 x 10^3) + (5 x 10^5)
- Adjust the powers of 10:
- Since 10^5 is greater than 10^3, we adjust the first number:
- 2 x 10^3 = 0.2 x 10^5
- Since 10^5 is greater than 10^3, we adjust the first number:
- Add the coefficients:
- 0.2 x 10^5 + 5 x 10^5 = 5.2 x 10^5
Conclusion
Therefore, (2 x 10^3) + (5 x 10^5) = 5.2 x 10^5. By following these steps, you can successfully add numbers expressed in scientific notation.
