256=$2^8$

$\sqrt{256} = \sqrt{2^8} = 2^{ \frac{8}{2} } =2^4=16$

Answer 2

$\begin{array}{c|c}\sf256&\sf2\\\sf128&\sf2\\\sf64&\sf2\\\sf32&\sf2\\\sf16&\sf2\\\sf8&\sf2\\\sf4&\sf2\\\sf2&\sf2\\\sf1\end{array}$

$\sf\sqrt{256}=\sqrt{2^2\cdot2^2\cdot2^2\cdot2^2}$

$\sf\sqrt{256}=2\cdot2\cdot2\cdot2$

$\boxed{\boxed{\sf \sqrt{256}=16}}$
