Question

The distance between the sun and Earth is approximately 93,000,000 miles, how do you write it in scientific notation?

Answer 1

`9.3*10^7`

To write in scientific notation, always put the dot after the first number that isn't `0`. Take out all the unnecessary `0`s.
Then you multiply by `10^x`
`x` is the number of times you have to move the dot to the left to find your original number back

Example : `320.8=3.208*10²`
