Question

Can you write 880000000 as standard form ?

Answer 1

`8.8 times 10^8` (Highly recommend that you read below!)

Explanation:

Standard form uses the fact that the decimal place value system is based on powers of `10` eg... `10^6 = 1000000` (six zeros)

So for yours you first count the zeros...

You have `7` so you would write it as `10^7`.

But we also need to know the digit in front. It is crucial that the first digit is between `1-10` because if it is not it is not written in standard form# Here's an example:

Write `50,000` in standard form.

`50,000` can be written as: `5 times 10,000`

`10,000` = `10 \times 10 \times 10 \times 10 = 10^4`

So: `50,000 = 5 \times 10^4`

Now we use this template of working out for your question:

`880000000` can be written as `8.8 times 100000000`
(we also need to multiply the second part by 10, which gives `10^8`)

`10000000 = 10 times 10 times 10 times 10 times 10 times 10 times 10 times 10 = 10^8`

So: `880000000 = 8.8 times 10^8`

Hope this helped you out!! :D
