D: 6x10-^3

1 answer

To divide numbers in scientific notation, you divide the coefficients and subtract the exponents.

3.3 x 10^4 / 5.5 x 10^7 can be rewritten as (3.3 / 5.5) x 10^(4-7).

3.3 / 5.5 = 0.6.

The exponent is 4-7 = -3.

Therefore, the answer is 0.6 x 10^(-3), which can be rewritten as 6 x 10^(-4).

So, the answer is B: 6 x 10^(-4).
