Question

 O valor da expressão : √3 + 2 √3 - (6 √7 -3 √ 7) . 2 é: com calculo​

Answer 1

Explicação passo-a-passo:

$\sf \sqrt{3}+2\sqrt{3}-(6\sqrt{7}-3\sqrt{7})\cdot2$

$\sf =\sqrt{3}+2\sqrt{3}-3\sqrt{7}\cdot2$

$\sf =\sqrt{3}+2\sqrt{3}-6\sqrt{7}$

$\sf =3\sqrt{3}-6\sqrt{7}$

$\sf =3\cdot(\sqrt{3}-2\sqrt{7})$

Answer 2

Oie, Td Bom?!

$= \sqrt{3} + 2 \sqrt{3} - (6 \sqrt{7} - 3 \sqrt{7} ) \: . \: 2$

$= 3 \sqrt{3} - 3 \sqrt{7} \: . \: 2$

$= 3 \sqrt{3} - 6 \sqrt{7}$
