Answer 1

To round the number 7,803,100 to the nearest place value, we need to identify the place value we're rounding to.

If we round to the nearest million, we look at the hundred thousand place, which is 8 in this case. Since 8 is five or greater, we round up.

So, 7,803,100 rounded to the nearest million is 8,000,000.

Next, to express this number in the form of a single digit times an integer power of 10, we can write:

\( 8,000,000 = 8 \times 10^6 \).

Thus, the final answer is:

8 \times 10^6.
