The answer is:

8,400,000

Explanation:

So you choose the first 2 significant digits, and if the 3rd digit under 5, you round the number down, if the 3rd digit is above 5, then you round the number up. If the 3rd digit is 5, you can round it up or down. In this case the 3rd digit is 2, we round the number to 84 and then we put the rest of the numbers as zeros. If after 84 we have 6 for example, then after we round up we'll have:8,500,000
