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

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:

$A:$ $"A:"$ $31.2 \times 10^{2} = 3120$ $31.2xx10^2 = 3120$

$B:$ $"B:"$ $3120 \times 10^{- 2} = 31.2$ $3120xx10^-2 = 31.2$

$C:$ $"C:"$ $0.312 \times 10^{3} = 312$ $0.312xx10^3 = 312$

$D$ $"D"$ $3.012 \times 10^{3} = 3012$ $3.012xx10^3 = 3012$

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 $x$ $x$ 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 :)
