Final answer:
The quotient of (22.8 x 10^-3) and (5.7 x 10^-6) is 4 x 10^3.
Step-by-step explanation:
To determine the quotient of (22.8 x 10-3) and (5.7 x 10-6) in scientific notation, we divide the coefficients and subtract the exponents. In this case, the quotient is (22.8 / 5.7) x 10-3-(-6) = 4 x 103. So the correct answer is option D, 4 x 103.
