answer:
To write 32,000,000 in scientific notation, we need to express it as a number between 1 and 10, multiplied by a power of 10.
1. Determine the decimal form:
- The given number is 32,000,000.
- To convert it to scientific notation, we need to move the decimal point to the right until there is only one non-zero digit to the left of the decimal point.
- So, we move the decimal point 7 places to the left: 32,000,000 becomes 3.2.
2. Determine the exponent:
- To find the exponent, count the number of places you moved the decimal point to the left.
- In this case, we moved it 7 places to the left.
- Since we moved the decimal point to the left, the exponent will be positive.
- Therefore, the exponent is 7.
3. Write in scientific notation:
- Putting it all together, 32,000,000 can be expressed in scientific notation as 3.2 × 10^7.
Therefore, 32,000,000 can be written as 3.2 × 10^7 in scientific notation.
