Answer:
3990000
Explanation:
1. we have to do is 4 × 10^6
= 40^6
= 4,000,000
2. we have to do the same step as first step 1 × 10^4
= 10^4
= 10,000
after finding the answer to both equations subtracts the big number from the small number, why? because the question asked "How many times larger is"
4,000,000 - 10,000 = 3,990,000
so the answer is 3,990,000
