Options

B 0.93 × 10⁸
C 9.3 × 10⁷
Correct Answer
D 9.3 × 10⁻⁷
Correct Answer

Option C is the correct answer.

Detailed Explanation

Scientific notation expresses a number as a value between 1 and 10 multiplied by a power of 10. For 93,000,000, the decimal point is moved 7 places to the left to get 9.3. Since the original number is large, the exponent is positive, giving 9.3 × 10⁷.

Hint

Write the number with one non-zero digit before the decimal point and count how many places the decimal moved to determine the exponent.
