Which numbers mentioned in this article are exact figures, which are approximated figures?

1. 8848m is a exact figure,-45C is a approximated figure, year 2010 is a exact figure, year 1856 , year 1955and year 1999 are exact figures. 8850m is a exact figure.

2. the Nepal's figures exact, years are exact, temperature is estimated and the height is also exact

3. 8848,8852 Year 2010,1856,1955,1999 And -45Degrees are exact figures. But 8850 is a approximate figure.

4. 1)8,848m
2)8,850m
3)three-year
4)-45C
5)4m

5. 8,848m is an approximate figure. -45C temperature is an approximate. 8,850 metres is also approximate. 1856,1955,1999 is an exact figure.

6. Exact: 8848m, 2010, 1856, 1955, 1999, 8850m, 2 countries
Approximated: 150 years, -45C, 4m, 3-year project

7. 8848m, 8850m and -45°C may be a approximated figure, 2010, 1856, 1955 and 1999 are exact numbers.

9. The years mentioned in the article are exact figures the measurements made by nepal and by the GPS is exact.

10. 8848m is an exact figure, -45C might be exact or an approximate figure, 4m is an approximate figure,, 1856, 1955, 1999 are exact figures

12. 8,848m -> approximate

2010 -> exact

-45C -> approximate

4m ->approximate

1856 -> exact

1955 -> exact

8,850 m ->approximate

150 years -> approximate

13. 8848n is not an exact figure. -45 degree celcius is an approximate figure. 4 m is an approximate figure. The years in the passage are also exact figures.

14. 8,848m is an approximated figure. -45C is an approximate figure. 1856,1955,1999 are exact figures.

15. More than 150 years, 8848m, next couple of years, 4m, 8850m, -45C Temperature -> Approximated Figure
Year 2010, 1856, 1955, and 1999, two countries, Three Year project

16. Year 2010, 1955 and 1856 are exact figures, 8848m is an approximated figure, -45C degrees is an approximated figure, 150 years is an approximated figure, 4m is a exact figure, 8850m is an approximated figure.

17. Year 2010,1856,1955,1999 are exact figure but more than 150 years ,8848m,8850m is approximated figure.

1. -45 c is a approximated figure

18. Exact: the years Approximate: 150 years, -45 degrees and the height of Mt Everest
