Explanation:
Detailed explanation-1: -A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650, 000, 000 can be written in scientific notation as 6.5 ✕ 10^8.
Detailed explanation-2: -5, 000, 000, 000 in scientific notation is 5 x 109. This is breaking the number into the digit times its place value. (Count the O’s.) The 4 is in the thousandths place, so multiplying by 10-3 (1/1000) is the same as dividing by 103 (1, 000).
