1.00 x 10-4
100 is already rounded to one significant figure.
To express 273 to one significant figure, you round it to the nearest ten. The first significant figure is 2, and since the digit following it (7) is 5 or greater, you round up. Therefore, 273 to one significant figure is 300.
It then is 40000 to one significant figure
It is 10
To express 961 to one significant figure, you round it to the nearest significant digit. The first significant digit in 961 is 9, and since the next digit (6) is 5 or greater, you round up. Therefore, 961 rounded to one significant figure is 1000.

It then is 40000 to one significant figure
200 Explanation: 2 is the one significant figure. The zeros are not significant. Round up because it is closer to 200 than to 100.
It is 10

To express 961 to one significant figure, you round it to the nearest significant digit. The first significant digit in 961 is 9, and since the next digit (6) is 5 or greater, you round up. Therefore, 961 rounded to one significant figure is 1000.
You round to the nearest tens place. In this case, 738 rounded to one significant figure is 700.
When expressing a number to one significant figure, you round the number to the nearest power of 10. In this case, 9862 to one significant figure would be 10,000. This is because the first digit from the left is 9, which is closer to 10 than 10000.
0.0712 rounded to one significant figure is 0.1. In this case, the first significant figure is the digit '7', but since we only want one significant digit, we round it based on the next digit, which is '1'. Thus, the final answer is expressed as 0.1.
