Question

Ѵ1,44 + Ѵ0,36 + Ѵ0,09=

Answer 1

Explicação passo-a-passo:

$\mathsf{\sqrt{1,44}+\sqrt{0,36}+\sqrt{0,09}}$

$\mathsf{1,2+0,6+0,3}$

$\mathsf{\approx{2,1}}$

Answer 2

Explicação passo-a-passo:

$\sf E=\sqrt{1,44}+\sqrt{0,36}+\sqrt{0,09}$

$\sf E=\sqrt{\dfrac{144}{100}}+\sqrt{\dfrac{36}{100}}+\sqrt{\dfrac{9}{100}}$

$\sf E=\dfrac{\sqrt{144}}{\sqrt{100}}+\dfrac{\sqrt{36}}{\sqrt{100}}+\dfrac{\sqrt{9}}{\sqrt{100}}$

$\sf E=\dfrac{\sqrt{12^2}}{\sqrt{10^2}}+\dfrac{\sqrt{6^2}}{\sqrt{10^2}}+\dfrac{\sqrt{3^2}}{\sqrt{10^2}}$

$\sf E=\dfrac{12}{10}+\dfrac{6}{10}+\dfrac{3}{10}$

$\sf E=\dfrac{12+6+3}{10}$

$\sf \red{E=\dfrac{21}{10}}~\Rightarrow$ em fração

$\sf \red{E=2,1}~\Rightarrow$ em número decimal
