Answer 1

b)

$\sqrt{400} = 20$

$\sqrt{784} = 28$

$\sqrt{441} = 21$

$\sqrt{676} = 26$

c)

$\sqrt{1600} = 40$

$\sqrt{1296} = 36$

$\sqrt{1764} = 42$

$\sqrt{2025} = 45$

Answer 2

Răspuns:

√400=20²=20·20=20

√784=28²=28·28=28

√441=21²=21·21=21

√676=26²=26·26=26

√1600=40²=40·40=40

√1296=36²=36·36=36

√1764=42²=42·42=42

√2025=45²=45·45=45
