3,560 into scientific notation

3.56 x 10^3

Explanation:

In order to put in in scientific notation, the number must be between 1-10 and must be multiplied by a power of 10. We can turn 3560 into a number 1-10 by moving the decimal up.

We move it up 3 spaces. 3.560

Since we moved it up 3 spaces, we need to multiply it by 10^3

3.56 x 10^3
