Answer:

The population rounded to the nearest ten-thousand is 180,000

Explanation:

To round off to the nearest ten-thousand, we check what number is at the ten thousand place and what comes at the thousand place,

We get the following table,


\left[\begin{array}{cccccc}Hundred-Thousand&Ten-Thousand&Thousand&Hundred&Ten&Unit\\1&7&9&2&1&3\end{array}\right]

So, at the ten thousand place, we get 7 and at the thousand place, we get 9

now, since 9 is greater than 5, we round up i.e, we add 1 to the ten thousand place, and get, 7 + 1 = 8,

so the population, rounded to the nearest ten-thousand is,

180,000
