Answer:
2,400,000 = 2.4 ×
Explanation:
First step is to decide where the decimal point will move to when it becomes scientific notation. We want to make this as large as we can without it being over 10. (It also cannot be less than 1) So, is this example, we cannot make it 0.24, because that is less than one. We also cannot make it 24, because that is more than 10. Hence, our coefficient will be 2.4.
Now rewrite the number, keeping all original zeros, but moving the decimal place to create this coefficient:
2.400000
Now, to decide by what number the 10 should be raised to (the exponent), count how many places to the left you have moved the decimal place, imagining that it was originally at the end of 2,400,000. ← like that
Counting the places, we have moved the decimal place 6 places to the left. Hence the scientific notation for 2,400,000 is:
2.4 ×
