Question

write 3,147 in scientific notation.

Explanation:

Step1: Recall scientific notation form

Scientific notation is in the form \( a \times 10^{n} \), where \( 1\leqslant|a|\lt10 \) and \( n \) is an integer.
For the number \( 3.147 \), we can see that \( a = 3.147 \) and since the number is already between \( 1 \) and \( 10 \), the exponent \( n = 0 \) (because \( 3.147=3.147\times10^{0} \)).

Answer:

\( 3.147\times10^{0} \)
