Final answer:
To calculate the quotient, divide the numbers and subtract the exponents. (2.40 X 10^2) divided by (3.0 X 10^-1) = 0.8 X 10^3.
Step-by-step explanation:
To calculate the quotient, we divide the two numbers by dividing their coefficients and subtracting the exponents of the powers of 10.
(2.40 × 102) divided by (3.0 × 10-1) = (2.40 / 3.0) × 102 - (-1) = 0.8 × 102 + 1 = 0.8 × 103
So the quotient is 0.8 × 103 in scientific notation.
