How can you tell if a number written in scientific notation is big or small?

Answer 1

If a number written in scientific notation has an exponent of 10 that is negative, then it is a small number; otherwise, it is a large number.

Answer 2

In scientific notation, a number is expressed as a decimal multiplied by a power of 10. To determine if a number is big or small, look at the power of 10. If the power is positive, the number is big, and if the power is negative, the number is small. The higher the magnitude of the power, the larger or smaller the number.
