Question

How do you write 314,207 in standard form?

Answer 1

`3.14207xx10^5`

Explanation:

Standard form requires only one digit before the decimal.

So , you need to write `314207` as `3.143207`.

But as you see they are not equal.

So , as we have shifted the decimal to left by `5` places , we just need to multiply it by `10^5` to make them equal.

So , in standard form `314207` is written as `3.14207 xx 10^5`.
