Final answer:
The result of dividing 8×106 by 4×103 shows that 8×106 is 2×103 times larger than 4×103, making the correct answer A. 2×103 times larger.
Step-by-step explanation:
To find out how many times larger 8×106 is than 4×103, we can divide the former by the latter:
(8×106) ÷ (4×103) = (8÷4) × (106÷10-3)
Calculate the numeric part and the powers of ten separately:
(8÷4) = 2
Using the rule for dividing powers of ten, subtract the exponents:
106÷10-3 = 106-3 = 103
Therefore, the result is 2 × 103, which indicates that 8×106 is 2×103 times larger than 4×103.
Thus, the correct answer is A. 2×103 times larger.
