Question

Two electronics students are converting values into scientific notation. Student A says that the number 29,000 is expressed as 2.9 × 104 in scientific notation. Student B says that the number 0.089 is expressed as 8.9 × 10−2 in scientific notation. Which of the following statements is correct? A. Neither of the two students is correct. B. Only Student A is correct. C. Both of the students are correct. D. Only Student B is correct.

Answer 1

Hello there! Both of the students are correct. This is because 10^4 is 10,000 and 10,000 * 2.9 = 29,000. 10^-2 is 0.01. 8.9 * 0.01 is 0.089. You can check on the calculator and see that both students are correct. The answer is C.
