Taylor's math teacher asks, "Which of the following numbers are written in scientific notation?" 19 3.17 7.99 times 10 Superscript 1 3.17 times 10 Superscript 1 Taylor says, "3.17 times 10 Superscript 1 is written in scientific notation." What is the correct answer? What error did Taylor make? The number 19 is also written in scientific notation. B. The number 7.99 times 10 Superscript 1 is also written in scientific notation. C. The number 3.17 times 10 Superscript 1 is not written in scientific notation. D. The number 3.17 is also written in scientific notation.
The correct answer is B. The number 7.99 times 10^1 is written in scientific notation.
Taylor made an error by thinking that 3.17 times 10^1 is written in scientific notation. However, in scientific notation, the number before the multiplication sign must be greater than or equal to 1 and less than 10. In this case, 3.17 is not within that range, so it is not written in scientific notation.
