The question
Question: write 600000 in scientific notation.
600000
1 What it looks like
Scientific notation is a number from 1 to under 10, times a power of 10.
a × 10n a: from 1 to under 10
2 Move the point
Moving the point 5 to the left made the number 100000 times smaller.
To make it the same again, we times by 100000.
That is 10⁵.
105 = 100000
So 600000 is 6.00000 × 10⁵.
= 6.00000 × 105
Zeros at the end, after the point, can go: 6.00000 is 6.
So we get 6 × 10⁵.
= 6 × 105
3 Check
Let's check: times 100000 moves the point 5 back to the right.
We get 600000 again!
6 × 100000 = 600000
Let's look back.
First: what it looks like.
Then: move the point.
Last: check.
Answer
= 6 × 105
