Wzór na przekątną kwadratu
[tex]d = a \sqrt{2} [/tex]
a)
[tex]a = 5 \\ a \sqrt{2} = 5 \sqrt{2} [/tex]
b)
[tex]a = 3 \sqrt{2} \\ a \sqrt{2} = 3 \sqrt{2} \times \sqrt{2} = 3 \sqrt{4} = 3 \times 2 = 6[/tex]
c)
[tex]a = 5 \sqrt{3} \\ a \sqrt{2} = 5 \sqrt{3} \times \sqrt{2} = 5 \sqrt{6} [/tex]
c)
[tex]a = 0.5 \sqrt{2} \\ a \sqrt{2} = 0.5 \sqrt{2} \times \sqrt{2} = 0.5 \sqrt{4} = 0.5 \times 2 = 1[/tex]
e)
[tex]a = 3.5 \\ a \sqrt{2} = 3.5 \sqrt{2} [/tex]
f)
[tex]a = \sqrt{8} \\ a \sqrt{2} = \sqrt{8} \times \sqrt{2} = \sqrt{16} = 4[/tex]
Myślę że pomogłem ;)
