Answer :
Final answer:
The product of the given numbers is 1677312000000000000000000, reached by multiplying the individual digits and then appending 12 zeros due to the thousands.
Explanation:
To calculate the product of 4000×5000×6000×7000×1000×9000×10,000×11,000×3000×6000×12,000×20,000, we can simplify the calculation by looking for patterns and using exponentiation where possible. First, let's group the thousands together to make it easier:
(4×5×6×7×1×9×10×11×3×6×12×20) × (1000^12)
To start, we can multiply the single-digit numbers together, and then the double-digit numbers:
4×5×6×7×9 = 5040
10×11×3×6×12×20 = 332640
Now, we can multiply these two results:
5040 × 332640 = 1677312000
Finally, we multiply this result by 1000^12 which is essentially adding 12 zeros to the end of our current product:
1677312000000000000000000
