Solución
To round the number 80710 to 2 significant figures, we follow these steps:
- Identify the first two significant figures in the number. In 80710, the first two significant figures are 8 and 0.
- Look at the digit immediately after the second significant figure (which is 7 in this case) to determine whether to round up or keep it the same.
- Since 7 is greater than 5, we round up the second significant figure (0) to 1.
Thus, rounding 80710 to 2 significant figures gives us 81.
Now, we express this in the correct format, which is 81000.
Therefore, the answer is 81000.

When rounding the number 80710 to two significant figures, you look at the first two digits (80) and then consider the next digit (7) to determine if you round up. Since 7 is greater than 5, you round up 80 to 81, giving you 81000. So, the correct answer is 81000!
Rounding can sometimes get tricky, especially with large numbers or those with zeros involved. A common mistake is to only rely on the first digits without considering what follows. Remember, the key to proper rounding is keeping an eye on the digit immediately after the one you’re rounding!
