Question

How do you write 4 hundred thousand in scientific notation?

Answer 1

`400 000=4.10^5`

Explanation:

First let's put numbers on words. 4 hundred thousands is 400 000. Scientific notation have to be compound with a number between 0 and 10, completed with zeros. So We have :
`400 000=4.10^5`

Answer 2

see answer below;

Explanation:

`400, 000 = 4.0 xx 10^5 -> "Scientific notation"`

counting the number of times you move the decimal points, it would give you the exponent value, for example;

If you are counting to the left, it means that the exponent value would be positive, and then counting to the right the exponent value would be negative..

Hence; `400, 000 = 4.0 xx 10^5` which means we counted to the right, five times, that results our exponential value to become `E 5 or 10^5`
