Answer 1

$a)\sqrt{400 } \\ \sqrt{2 {}^{2} \times {5}^{2} \times {2}^{2}} \\ \sqrt{ {2}^{4} \times {5}^{2} } \\ {2}^{2} \times 5 = 20$

$b) \: \sqrt{900} \\ \sqrt{ {2}^{2} \times {5}^{2} \times {3}^{2} } \\ 2 \times 3 \times 5 = 30$

$c) \: \sqrt{256} \\ \sqrt{ {2}^{8} } \\ {2}^{4} = 16$

$d) \: \sqrt{1024} \\ \sqrt{ {2}^{10} } \\ {2}^{5} = 32$

Ahí tienes la resolución completa
