Question

Alguém pode me responder?

Answer 1

Resposta:

Explicação passo-a-passo:

$x1^{2}=1^{2}+1^{2}\\\\x1^{2}=1+1\\\\x1^{2}=2\\\\x1=\sqrt{2}$

$x2^{2}=x1^{2}+1^{2}\\\\x2^{2}=(\sqrt{2})^{2}+1^{2}\\\\x2^{2}=2+1\\\\x2^{2}=3\\\\x2=\sqrt{3}$

$x3^{2}=x2^{2}+1^{2}\\\\x3^{2}=(\sqrt{3})^{2}+1\\\\x3^{2}=3+1\\\\x3^{2}=4\\\\x3=\sqrt{4}\\\\x3=2$

$x1+x2+x3=\sqrt{2}+\sqrt{3}+2$
