The exact value of 400 comma 000 times 200 is 8. (use scientific notation. use the multiplication symbol in the math palette as needed.)

The scientific notation of 8,000,000 is 8 × 10^6

Step-by-step 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

80x^8−68x^6+16^5−20x^4−4x^3+8x^2
