Answer
$5.63 \times 10^{5}$
Work Step by Step
The first step is to count the number of umbers following the first digit. In this case there are five.
Place the decimal after the first digit and write the remaining non-zero integers that follow it.
5.63
Now multiply this by 10 to the power of trailing digits (5).
$5.63 \times 10^{5}$
