Write 5.08 × 10^3 as a normal number

Step by step

The question

Question: write 5.08 × 10³ as a normal number.

1 Read the power

10³ is 1000.

Times 1000 makes the number bigger, so the point moves 3 places to the right.

2 Move the point

There are not enough digits after the point.

We write 1 zero at the end.

Zeros there do not change the number.

The point is at the end now, so we leave it out.

So 5.08 × 10³ = 5080.

Careful!

The power is not the number of zeros.

It is how many places the point moves.

5.08 already has 2 digits after the point.

3 Check

Let's check: times 1000.

5.08 times 1000 is 5080.

It works!

Let's look back.

First: read the power.

Then: move the point.

Last: check.
