Question

What is 3900000000 in standard form?? Help :)))

Answer 1

`3.9` ×
`10^9`

Explanation:

To find out the standard form we simply have to look at the first digits in the number greater than 0 and count how many digits are after it!

Example:

The number we are given is 3900000000.

We can see that the first digit greater than 0 is the 3 and we put a decimal point there, so now we count how many digits there are after it.

Which is 9!!

This means our answer is
`3.9` ×
`10^(9)`

Hope this helps, have a lovely day! :)
