1. C. 227000mm
You have to use conversion factors
knowing that 1m=1000mm
multiply 227 by 1000 and you will get the answer, like this:
[tex]227m = \frac{1000mm}{1m} = 227000[/tex]
2. C. 2.66x10^6
move the decimal (in this case it would be after the last zero) until you have a coefficient between 1 and 10, in this case 2.66. The number of places you had to move to the decimal point is the exponent. Since we had to move the decimal 5 places to the left, the exponent is 5.
3. C. 2.66x10^-4
Start by moving the decimal place until you have a coefficient between 1 and 10, in this case 2.66. Since we had to move the decimal 4 places to the right, the exponent is -4.
