Answer 2

$\large\boxed{\begin{array}{l} \begin{array}{r|l} 100&2 \\ 50&2 \\ 25&5 \\ 5&5 \\ 1 \end{array} \\ \\ \sqrt{100} = \sqrt{2 {}^{2} \cdot 5 {}^{2} } \\ \sqrt{100} = 2 \cdot5 \\ \sqrt{100} = 10\end{array}}$

$\large\boxed{\begin{array}{l} \begin{array}{r|l} 400&2 \\ 200&2 \\ 100&2 \\ 50&2 \\ 25&5 \\ 5&5 \\ 1 \end{array} \\ \\ \sqrt{400} = \sqrt{2 {}^{2} \cdot2 { }^{2} \cdot5 {}^{2} } \\ \sqrt{400} = 2 \cdot2 \cdot5 \\ \sqrt{400} = 20\end{array}}$

$\large\boxed{\begin{array}{l} \begin{array}{r|l}900 &2 \\ 450&2 \\ 225&3 \\ 75&3 \\ 25&5 \\ 5&5 \\ 1 \end{array} \\ \\ \sqrt{900} = \sqrt{2 {}^{2} \cdot3 { }^{2} \cdot5 {}^{2} } \\ \sqrt{900} = 2 \cdot3 \cdot5 \\ \sqrt{900} = 30\end{array}}$
