The question
Question: write 7.008 × 10³ as a normal number.
7.008 × 103
1 Read the power
10³ is 1000.
Times 1000 makes the number bigger, so the point moves 3 places to the right.
103 = 1000
right 3 places
2 Move the point
We write the digits.
= 7.008
The point is at the end now, so we leave it out.
So 7.008 × 10³ = 7008.
= 7008
3 Check
Let's check: times 1000.
7.008 times 1000 is 7008.
It works!
7.008 × 1000 = 7008
Let's look back.
First: read the power.
Then: move the point.
Last: check.
Answer
= 7008
