1. Move the decimal point:

* Start with 3480. Since it's a whole number, the decimal point is implied to be at the end (3480.).

* Move the decimal point to the left until you have a number between 1 and 10. In this case, you'll move it three places to the left: 3.480

2. Count the decimal places:

* You moved the decimal point three places to the left.

3. Write in scientific notation:

* The number is now 3.480.

* Multiply this by 10 raised to the power of the number of places you moved the decimal (3).

Therefore, 3480 in scientific notation is 3.48 x 10³
