I recently had a question that read:
Express 703 in standard form
Is this a trick question? The number is already in standard form, isn't it?
This is not a trick question! The number 703 is not in standard form.
703 is read "Seventy to the power three". It means
70 × 70 × 70
which is equal to 343 000
A number in standard form looks like this:
| Where A is a number between 1 and 10,
and n is a positive or negative whole number
So the number 343 000 in standard form is
3.43 × 105
Your calculator may show this as
but this is just calculator shorthand. You should not copy this down.
Instead, you should write the standard form number as 3.43 × 103 to be correct.
