Question

(√3-√2)×(√3+√2)+(√5-3)×(√5+3)​

Answer 1

$(\sqrt{3} { }^{2} - \sqrt{2} { }^{2} ) + ( \sqrt{5} {}^{2} - 3 {}^{2} )$

Answer 2

Răspuns:

    -3

Explicație pas cu pas:

    $(\sqrt{3}-\sqrt{2})*(\sqrt{3}+\sqrt{2})+(\sqrt{5}-3)*(\sqrt{5}+3)$

    $\sqrt{3}^2-\sqrt{2}^2+\sqrt{5}^2-3^2$

    $3-2+5-9=\boxed{-3}$
