Is the number 1,997 prime?
Select the correct answer.
(a) Prime
(b) Not prime
To select the correct answer, we need to write each of the given options in decimal notation. Decimal notation is a way of representing numbers using the base-10 system, which includes digits from 0 to 9.
Let's write each option in decimal notation:
0.00005 - This is already written in decimal notation.
-50000 - This is a negative number, but it is also written in decimal notation.
-5000 - Similar to the previous option, this is a negative number in decimal notation.
0.0005 - Again, this is already written in decimal notation.
So, all four given options are already written in decimal notation.
