Question

(√3+√2)²

ajuda aí, pô!

Answer 1

Lembre-se que $(a + b)^{2}$ = $a^{2} + 2ab + b^{2}$

Portanto:
$(\sqrt{3} + \sqrt{2})^{2}$ = $\sqrt{3}^{2} + 2\sqrt{3}\sqrt{2} + \sqrt{2} ^{2}$$(\sqrt{3} + \sqrt{2})^{2} = (\sqrt{3})^{2} + 2\sqrt{3}\sqrt{2} + (\sqrt{2}) ^{2} = 3 + 2\sqrt{6} + 2 = 5 + 2\sqrt{6}$
