Question

quanto é [(1/2)^2 + 1/5] divido pela raiz quadrada de 9/4??

Answer 1

Explicação passo-a-passo:

$\sf E=\dfrac{\Big(\frac{1}{2}\Big)^2+\frac{1}{5}}{\sqrt{\frac{9}{4}}}$

$\sf E=\dfrac{\frac{1}{4}+\frac{1}{5}}{\frac{3}{2}}$

$\sf E=\dfrac{\frac{5+4}{20}}{\frac{3}{2}}$

$\sf E=\dfrac{\frac{9}{20}}{\frac{3}{2}}$

$\sf E=\dfrac{9}{20}\cdot\dfrac{2}{3}$

$\sf E=\dfrac{18}{60}$

$\sf E=\dfrac{18\div6}{60\div6}$

$\sf E=\red{\dfrac{3}{10}}$
