Write 9.1 × 10^1 as a normal number

Step by step

The question

Question: write 9.1 × 10¹ as a normal number.

1 Read the power

10¹ is 10.

Times 10 makes the number bigger, so the point moves 1 place to the right.

2 Move the point

We write the digits.

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

So 9.1 × 10¹ = 91.

3 Check

Let's check: times 10.

9.1 times 10 is 91.

It works!

Let's look back.

First: read the power.

Then: move the point.

Last: check.
