PFVRR ME AJUDEM, é muito importante

Answer 1

Resposta:

$A = \sqrt{ \left ( \dfrac{-\,1}{2} \right )^{2} \times \left ( \dfrac{3}{2} \right )^{-\,2} + \left ( \dfrac{1}{2} \right )^{3} \times \left ( \dfrac{1}{2} \right )^{-\,2} } }$

$A = \sqrt{ \left ( \dfrac{1}{4} \right ) \times \left ( \dfrac{2}{3} \right )^{,2} +\left ( \dfrac{8}{27} \right )\times \left ( \dfrac{2}{1} \right )^{2} } }$

$A = \sqrt{ \left ( \dfrac{1}{4} \right ) \times \left ( \dfrac{4}{9} \right ) +\left ( \dfrac{8}{27} \right ) \times \left ( \dfrac{4}{1} \right)}}$

$A = \sqrt{ \left ( \dfrac{4}{36} \right ) +\left ( \dfrac{32}{27} \right ) }$

$A = \sqrt{ \left ( \dfrac{12}{108} \right ) +\left ( \dfrac{128}{108} \right ) }$

$A = \sqrt{ \left ( \dfrac{12 + 128}{108} \right ) }$

$A = \sqrt{ \left ( \dfrac{140}{108} \right ) }$

$A = \sqrt{ \left ( \dfrac{35}{27} \right ) }$
