Evaluate the positive difference between 0.005348 and correct to 3 significant figures and 0.005384 correct to 3 significant figures

Answer 1

To evaluate the positive difference, we subtract the smaller value from the larger value. In this case, we have:

0.005384 - 0.005348 = 0.000036

Now, we need to round this value to 3 significant figures. In order to do so, we count the number of significant figures in the original values:

0.005348 has 4 significant figures
0.005384 has 4 significant figures

The least number of significant figures in the original values is 4. Therefore, we round the positive difference to 4 significant figures:

0.000036 to 4 significant figures is 0.00004

So, the positive difference between 0.005348 and 0.005384, correct to 3 significant figures, is 0.00004.
