Using the rules for significant figures, the correct answer for the expression 0 . 02858 × 0 . 112 0 . 5702 will be:

Options

  1. A0 . 005613
  2. B0 . 00561
  3. C0 . 0056
  4. D0 . 006

Correct answer

B. 0 . 00561

Step-by-step solution

In multiplication and division, the result must be reported with no more significant figures as in the measurement with few significant figures 0 . 02858 × 0 . 112 0 . 5702 = 0 . 000561 (Or) Reported answer should not be more precise than the least precise term in calculations, so there should be three significant figures in reported answer.
