#### Answer:

#### Explanation:

So this involves the use of rearranging the equation in terms of moving the "decimal".

If we were to reword these values, it would look like this:

#"A:"# #31.2xx10^2 = 3120#

#"B:"# #3120xx10^-2 = 31.2#

#"C:"# #0.312xx10^3 = 312#

#"D"# #3.012xx10^3 = 3012#

These values were rearranged like this because the exponent tells me so. With a positive exponent, you can "move" the decimal to the right an

A negative exponent is the same but to the left.

Now if we were to order them in ascending order (smallest to greatest):

Hope this helps :)
