"B", "C", "D", "A"B,C,D,A.

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:"A: 31.2xx10^2 = 312031.2×102=3120

"B:"B: 3120xx10^-2 = 31.23120×102=31.2

"C:"C: 0.312xx10^3 = 3120.312×103=312

"D"D 3.012xx10^3 = 30123.012×103=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 xx amount of value places.

A negative exponent is the same but to the left.

Now if we were to order them in ascending order (smallest to greatest): "B", "C", "D", "A"B,C,D,A.

Hope this helps :)
