Question

convert to scientific notation: 43,000,000

Explanation:

Step1: Recall scientific notation form

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

Step2: Rewrite 43,000,000 in scientific notation

First, move the decimal point to the left until there is only one non - zero digit to the left of the decimal point. For 43,000,000, moving the decimal point 7 places to the left gives \( 4.3 \). The number of places we moved the decimal point is the exponent \( n \) in \( 10^{n} \). Since we moved the decimal point 7 places to the left, \( n = 7 \). So, 43,000,000 in scientific notation is \( 4.3\times10^{7} \).

Answer:

\( 4.3\times10^{7} \)
