Question

me ajudem pfvrrr com urgência​

Answer 1

Resposta:

a

$(\frac{3}{4})^1 + \sqrt{\frac{25}{16}} + \frac{\sqrt{36} }{4}\\\frac{3}{4} + \frac{5}{4} + \frac{6}{4}\\\frac{3+ 5 + 6}{4}\\\frac{14}{4}$

b

$(\frac{2}{3})^2 - \sqrt{\frac{49}{81}} + \sqrt{\frac{64}{9}} + (\frac{5}{6})^2\\ \frac{4}{9} - \frac{7}{9} + \frac{25}{36}\\\frac{-3}{9} + \frac{25}{36}\\\frac{-15+ 72}{5}\\\frac{57}{5}$
