Question #b4c8b

Answer 1

`"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:"` `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 `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"`.

Hope this helps :)
