Question

to determine whether a number is written in scientific notation what test can you apply to the first factor and what test can you apply to the second factor

Answer 1

If the number has one decimal place.

If the second factor is divisible by 10

Explanation:

Scientific notation is generally written like x*10^y.

An example of this is 3.2*10^2

The first number always only has one number in the 1's place, and the second number is always ten to the power of something.
