Answer: 2.12 ×
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 . This gives us our answer.

Translate the statements to algebraic expression
Represent the power with x;
So, the left hand side is
<em>Power of 10: </em><em />
<em>Times n: </em><em />
<em />
The right hand side is:
<em>0.1515 * power of 10: </em><em />
Equate the right hand side to the left:
Hence;
