Question

a total 7,803,100 tourists visited country A from the year 2018 to the year 2020. round to the nearest place value then express this number in the form of a single digit times an integer power of 10

Answer 1

To round the number 7,803,100 to the nearest place value, we need to look at the digit in the hundred thousands place, which is 8. Since 8 is 5 or greater, we round up the million digit (7) by one.

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

Next, we express 8,000,000 in the form of a single digit times an integer power of 10:

\[
8,000,000 = 8 \times 10^6
\]

So, the final answer is:

\[
8 \times 10^6
\]
