ME AJUDEM POR FAVOR!!!

Answer 1

Resolva:


A. (1/2)²+2/3-5=>
$\frac{1}{4} + \frac{2}{3} - 5 \\ \\ - \frac{49}{12}$

B. √36/25-(7/2)-1=>
$\frac{6}{25} - \frac{7}{2} - 1 = \\ \\ - \frac{213}{50}$
C. 6-¹ +5/3×1/2=>
$\frac{1}{6} + \frac{5}{6} = \\ \\ 1$
D. √64/4 - 3/5·(-2/3)¹=>
$\frac{8}{4} - \frac{3}{5} \times ( - \frac{2}{3} ) = \\ \\ \frac{8}{4} + \frac{1}{5} \times 2 = \\ \\ \frac{8}{4} + \frac{2}{5} = \\ \\ \frac{12}{5}$

E. (-2/3)·1/2+4÷(3/4)=>
$- \frac{1}{3} + 4 \times \frac{4}{3} = \\ \\ - \frac{1}{3} + \frac{16}{3} = \\ \\ 5$
F. 4¹+1/3-(1/5)-²+4=>

$4 + \frac{1}{3} - 5 ^{2} + 4 = \\ \\ 4 + \frac{1}{3} - 25 + 4 = \\ \\ - 17 + \frac{1}{3} = \\ \\ - \frac{50}{3}$
