Answer:
7.25 x 10⁹
Step-by-step explanation:
- The steps are as follows:
Move the decimal point to the left until there is only 1 digit on the left of the decimal point. See what that number is , call it a
- Count the number of places you have moved the decimal. Call it b
- Then the number in scientific notation is a x 10^b
For 7,250,000,000 , you have to move 9 places to the left to get 7.25 so the number in scientific notation is 7.25 x 10⁹
