Question

Quizplus · Accepted Answer

Rounding off to four significant figures, we keep the first four non-zero digits and adjust the last one based on the digit that follows it. Here, the first four non-zero digits are 5075. Since the digit after 5075 is 6 (which is greater than 5), we round up the last significant figure to 8, resulting in 5.076. However, to express it with four significant figures, we use scientific notation: 5.076 becomes 5.076 × 10^6, which is closest to option D, considering it likely contains a typographical error in the representation of scientific notation.
