b) v= 7

 

c) v= 10

 

d) v= 20

 

e) v= 30

Answer 1

$a)\sqrt{5}=2,2360...\Longrightarrow\sqrt{5}\approx2\\\\b)\sqrt{7}=2,6457...\Longrightarrow\sqrt{7}\approx3\\\\c)\sqrt{10}=3,1622...\Longrightarrow\sqrt{10}\approx3\\\\d)\sqrt{20}=4,4721...\Longrightarrow\sqrt{20}\approx4\\\\e)\sqrt{30}=5,4772...\Longrightarrow\sqrt{30}\approx5$
