3√20+√32 − 2√45+√50=

3√4.5+√16.2 − 2√5.9+√25.2=

3.2√5+4√2 − 2.3√5+5√2=

6√5 + 4√2 − 6√5 + 5√2=

9√2

Answer 2

Resposta:

$9\sqrt{2}$

Explicação passo-a-passo:

3√20+√32 − 2√45+√50=>$3\sqrt{5.2^{2} } + \sqrt{2^{2}.2 .2^{2} }-2\sqrt{3^{2}.5 } +\sqrt{5^{2} .2} => 3.2\sqrt{5} +2.2\sqrt{2} - 2.3\sqrt{5} + 5\sqrt{2} => 6\sqrt{5} +4\sqrt{2} - 6\sqrt{5} + 5\sqrt{2} => 6\sqrt{5} - 6\sqrt{5} + 5\sqrt{2} +4\sqrt{2}=> 9\sqrt{2}$
