Question

How do you know if a number isn't a scientific notation ?

Answer 1

Scientific notation has a certain form: like 1.016X10^6
You can have only a single digit to the left of the decimal point.

Answer 2

So if it doesn't have a single digit to the left of the decimal point it is NOT an scientific notation ?

Answer 3

Not technically. I believe it is just called exponential notation at that point.

Answer 4

I still do not understand how you know if it is not a scientific notation?

Answer 5

If it doesn't look like that... it is not scientific notation. Do you have an example?

Answer 6

A. 0.023 × 10^-5
B. 1.85 x 10^-90
C. 3.75 x 10^17
D. 9.99 x 10^13

Answer 7

The digit to the left has to be a non- zero digit... thank you for the example. It triggered a specific rule.

Answer 8

So A would be the one that is not an scientific notation?

Answer 9

correct
