Answer:
The scientific notation of 8,000,000 is 8 × 10^6
Explanation:
* Lets explain the meaning of the scientific notation
- Scientific notation is a way of writing very large or very small numbers
- A number is written in scientific notation when a number between 1
and 10 is multiplied by a power of 10
- Ex: 650,000,000 can be written in scientific notation as
6.5 × 10^8
- We put a decimal points to make the number between 1 and 10 and
then count how many places from right to left until the decimal point
The decimal point between 6 and 5 to make the number 6.5 and
there are 8 places from the last zero to the decimal point
* Lets solve the problem
∵ The exact value of 400,000 × 200 = 8,000,000
- Put the decimal point before 8 and count how many places from
the last zero to the decimal point
∵ There are six places from last zero to the decimal point
∴ The scientific notation of 8,000,000 is 8 × 10^6
