Answer

Explanation:

Step1: Recall scientific - notation form

Scientific notation is $a\times10^{n}$, where $1\leqslant|a|\lt10$ and $n$ is an integer.

Step2: Move the decimal point

For the number 34500, move the decimal point 4 places to the left to get $a = 3.45$. Since we moved the decimal point 4 places to the left, $n = 4$.

Answer:

$3.45\times10^{4}$
