Final answer:
To correctly divide two numbers in scientific notation, you divide their coefficients and subtract the exponents. The correct answer for the division of 9.2 x 10^8 by 4 x 10^-3 is 2.3 x 10^11, not 2.4 x 10^5.
Step-by-step explanation:
The question involves dividing two numbers expressed in scientific notation. To find the correct answer, we divide the coefficients (the numbers before the powers of ten) and subtract the exponent of the denominator from that of the numerator. In this case, we divide 9.2 by 4 and subtract -3 from 8:
(9.2 ÷ 4) × 10^(8 - (-3)) = 2.3 × 10^11
So the correct answer is 2.3 × 10^11, not 2.4 × 10^5. Therefore, the quotation of 9.2 x 10^8 and 4 x 10^-3 is incorrect as provided by the friend.
