The square root of 56 is approximately:

$\sqrt{56} \approx 7.483$

Since 56 is not a perfect square, the square root is an irrational number, meaning it cannot be expressed as a simple fraction. It can also be simplified as follows:

$\sqrt{56} = \sqrt{4 \times 14} = \sqrt{4} \times \sqrt{14} = 2\sqrt{14}$

Thus, the simplified form is $2\sqrt{14}$, and the decimal approximation is about 7.483.
