Answer:  2.12 × [tex]10^{-3}[/tex]

               The coefficient (in green) will be 2.12

Step-by-step explanation:

     Scientific notation is written by multiplying the number by a power of 10. This number is a number between 1 and 10.

     Since this is a smaller number, we will be multiplying it by a power of 10 to a negative number.

    To get this value to a number between 1 and 10, we must multiply it by 10 3 times (also shown as 10³) which gives us 2.12.

    To get back to the original value, we multiply this by [tex]10^{-3}[/tex]. This gives us our answer.
