Answer 2

The largest place value of the numeric part of this quantity is the million place value.

Answer 3

To round 7,803,100 to the nearest place value, we need to look at the digit in the millions place, which is 7.

Since the digit to the right of 7 is 8, which is greater than or equal to 5, we need to round up.

Therefore, rounding 7,803,100 to the nearest million gives us 8,000,000.

In the form of a single digit times an integer power of 10, 8,000,000 can be written as 8 x 10^6.
