The number 0.002 expressed in exponential notation is A) 2 * 10³ B) 2 * 10⁴ C) 2 * 10^-³ D) 2 * 10^-⁴ E) none of these

Question

Quizplus · Accepted Answer

The general form of exponential notation is a × 10^n, where a is a number between 1 and 10 (excluding 10 itself) and n is an integer. To convert 0.002 to exponential notation, we can move the decimal point three places to the right to get 2, and then add a negative exponent of 3 to denote the number of decimal places moved. Therefore, 0.002 in exponential notation is 2 × 10^-3. Written in FUPA notation, this is 2 F1F1F1S1 × F1F1F10 10^-³, which corresponds to choice C.
