Question

1- Responda as questões corretamente:

Answer 1

Explicação passo-a-passo:

1) $\sf M_G=\sqrt[4]{2\cdot3\cdot4\cdot7}$

$\sf M_G=\sqrt[4]{168}$

$\sf M_G=3,6$

2) $\sf M_G=\sqrt[4]{3\cdot12\cdot16\cdot36}$

$\sf M_G=\sqrt[4]{2^8\cdot3^4}$

$\sf M_G=\sqrt[4]{(2^2\cdot3)^4}$

$\sf M_G=2^2\cdot3$

$\sf M_G=4\cdot3$

$\sf M_G=12$

Letra A

3) $\sf x^2=8\cdot18$

$\sf x^2=144$

$\sf x=\sqrt{144}$

$\sf x=12~cm$

4) $\sf M_G=\sqrt[3]{3\cdot5\cdot12}$

$\sf M_G=\sqrt[3]{180}$

$\sf M_G=5,65$

Letra A
