Understanding Scientific Notation

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. This notation is commonly used in mathematics, physics, and engineering to simplify calculations and make it easier to understand and compare large numbers.

What is the Scientific Notation Formula?

The scientific notation formula is:

a × 10^n

Where:

  • a is the coefficient (a number between 1 and 10)
  • n is the exponent (a power of 10)

Converting 752,500 to Scientific Notation

To convert 752,500 to scientific notation, we need to move the decimal point to the left until we have a number between 1 and 10. We also need to keep track of the number of places we moved the decimal point, which will be the exponent.

Step 1: Move the Decimal Point

Let's move the decimal point 5 places to the left to get a number between 1 and 10:

7.525 × 10^5

Step 2: Determine the Exponent

Since we moved the decimal point 5 places to the left, the exponent will be 5.

Step 3: Write the Scientific Notation

Now we can write 752,500 in scientific notation:

7.525 × 10^5

Example of Scientific Notation in Real-Life Applications

Scientific notation is commonly used in real-life applications such as:

  • Measuring the distance between stars in space

  • Not keeping track of the number of places the decimal point was moved

Conclusion

Writing 752,500 in scientific notation involves moving the decimal point to the left until we have a number between 1 and 10 and keeping track of the number of places we moved the decimal point. The resulting scientific notation is 7.525 × 10^5. Scientific notation is a powerful tool for simplifying calculations and making it easier to understand and compare large numbers.
