Question

express the number 26.7 in scientific notation. 2.67 × 10⁻² 2.67 × 10⁻¹ 2.67 × 10¹ 2.67 × 10² 26.7 is already written in scientific notation

Explanation:

Step1: Recall scientific notation rules

Scientific notation is in the form \( a \times 10^n \), where \( 1 \leq |a| < 10 \) and \( n \) is an integer.

Step2: Convert 26.7 to scientific notation

To get \( a \) between 1 and 10, we move the decimal point 1 place to the left: \( 26.7 = 2.67 \times 10^1 \) (since moving the decimal left 1 place means multiplying by \( 10^1 \)).

Answer:

C. \( 2.67 \times 10^1 \) (assuming the options are labeled A to E with the third option being \( 2.67 \times 10^1 \))
