$5.63 \cdot {10}^{2}$

#### Explanation:

Scientific notation (also called exponential notation) is to write a number in the form of
$a \cdot {10}^{x}$

where
a: $1 \le a < 10$
x: the number of places that we have to move the decimal point.

So as for number 563, the decimal point has to be moved 2 places

Therefore,
$5.63 \cdot {10}^{2}$
