Final answer:
The quotient of (22.8 × 10−3) ÷ (5.7 × 10−6) is 4 × 10³ in scientific notation.
Step-by-step explanation:
To determine the quotient of (22.8 × 10−3) ÷ (5.7 × 10−6) and express the answer in scientific notation, we first perform the division of the numbers and then the powers of 10 separately.
For the numerical part, we have 22.8 ÷ 5.7 which equals 4.
For the exponent part, we subtract the exponents because it's division: -( -3 - ( -6)) which simplifies to -3 + 6 equal to 3.
Combining both parts, the quotient is 4 × 10³.
Therefore, the quotient in scientific notation is 4 × 10³.
