How do you write the standard number 862,900 in scientific notation?

8.629 * 10^5

Step-by-step explanation:

862,900

Scientific notation is of the form a * 10 ^b where a is between 1 and less than 10

Move the decimal 5 places to the left so that there is one number before the decimal

Since we moved the to left the 5 is positive and it is our value for b

8.62900 * 10 ^5

The zeros at the end of the decimal are extra and can be left off

8.629 * 10^5
