The correct answer is c) very small and very large
Let's see this with a few examples: 1) if we have a very small number, such as [tex]0.0000000001[/tex] we see that we can write it easily by using the scientific notation: [tex]1\cdot 10^{-10}[/tex] 2) Similarly, if we have a very large number: [tex]10000000000[/tex] we see that we can write it easily by using again the scientific notation: [tex]1 \cdot 10^{10}[/tex]
