Question

A total of 7,803,100 tourists visited country a from the year 2018 to the year 2020 round to the nearest space 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 thousand (which is the space place value), we look at the digit in the hundreds place, which is 1. Since 1 is less than 5, we round down.

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

Next, to express 7,803,000 in the form of a single digit times an integer power of 10, we can rewrite it as:

\[
7,803,000 = 7.803 \times 10^6
\]

So, the final answer is:

**7.803 x 10^6**.
