Question

How do you write `480,000` in scientific notation?

Answer 1

`4,8xx10^5`

Explanation:

There is always 1 digit in front of the comma in scientific notation, so we count how many times we must move the comma front he end of the number to get it to 1 digit in front.

Answer 2

`4.8 xx 10^5`

Explanation:

scientific notation is a means of expressing very large or very small numbers in a shorthand form

the standard form is a x `10^n`where a must be a number between 1 and 10 and n is an integer,

first write 480000 as a number between 1 and 10 ie. 4.8

now we have to multiply by `10^5` to retain the value of the original.

so 480000 = 4.8 x `10^5`
