Math Problem Statement
How do I convert numbers from standard notation to scientific notation?
Solution
To convert numbers from standard notation to scientific notation, follow these steps:
Steps for Conversion:
-
Identify the Decimal Position: For a given number, find where the decimal point is (even if it’s not explicitly written, for example in whole numbers).
-
Move the Decimal: Move the decimal point to the right or left so that only one non-zero digit remains to the left of the decimal point. This new number will be between 1 and 10.
-
Count the Moves: Count how many places you moved the decimal point. This number will be the exponent of 10.
- Positive Exponent: If you moved the decimal to the left (for numbers larger than 1), the exponent is positive.
- Negative Exponent: If you moved the decimal to the right (for numbers smaller than 1), the exponent is negative.
-
Write the Number: The final form is , where:
- is the number between 1 and 10.
- is the exponent indicating how many places you moved the decimal.
Example 1: Converting 25,000 to scientific notation
- The decimal point in 25,000 is at the end (25,000.0).
- Move the decimal point 4 places to the left to get 2.5.
- Since we moved 4 places to the left, the exponent is .
Result:
Example 2: Converting 0.0036 to scientific notation
- The decimal point is already in place (0.0036).
- Move the decimal point 3 places to the right to get 3.6.
- Since we moved 3 places to the right, the exponent is .
Result:
