Question

what is 79, 300 written in scientific notation? a. $7.93 \times 10^4$ b. $7.93 \times 10^5$ c. $79.3 \times 10^4$ d. $79.3 \times 10^5$

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 79300 to scientific notation

Move the decimal point 4 places to the left to get \( a = 7.93 \), so \( n = 4 \). Thus, \( 79300 = 7.93 \times 10^4 \).

Answer:

A. \( 7.93 \times 10^4 \)
