Write 7.25 × 10^2 as a normal number

Step by step

The question

Question: write 7.25 × 10² as a normal number.

1 Read the power

10² is 100.

Times 100 makes the number bigger, so the point moves 2 places to the right.

2 Move the point

We write the digits.

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

So 7.25 × 10² = 725.

3 Check

Let's check: times 100.

7.25 times 100 is 725.

It works!

Let's look back.

First: read the power.

Then: move the point.

Last: check.
