Question

how do you write 1,860 in scientific notation? × 10

Explanation:

Step1: Rewrite number as product

To write a number in scientific - notation, we express it as $a\times10^{n}$, where $1\leqslant a<10$ and $n$ is an integer. For 1860, we move the decimal point 3 places to the left to get $a = 1.86$.
$1860=1.86\times1000$

Step2: Express 1000 as power of 10

Since $1000 = 10^{3}$, then $1860=1.86\times10^{3}$.

Answer:

$1.86\times10^{3}$
