In scientific notation, a number is expressed as \( a \times 10^b \). What is the range of values for \( a \)?

  1. A
    \( 0 \le a < 10 \)
  2. B
    \( 1 \le a \le 10 \)
  3. C
    \( 1 \le a < 10 \)
  4. D
    \( 0 < a \le 1 \)
View Answer & Solution

Correct answer · Option C

\( 1 \le a < 10 \)

Explanation

By definition of standard scientific notation, every number is expressed as \( a \times 10^b \), where \( a \) is a number between 1 and 10 (\( 1 \le a < 10 \)).
