B) 2/5 ÷ 3/6 . 3/4
C) √81 + {2.[3+4.(6-2)+(8+3).(5-2)]}
D) 2^3 + 3^2 . 4^2 + 24 ÷ 2
E) 2/4 +. 2^3 - 1/5
F) √49-√25.2^4 +5

Answer 1

Resposta:

Explicação passo a passo:

A)$\frac{5}{8} +\frac{3}{12} =\frac{15+6}{24} =\frac{21}{24}$

B) $\frac{2}{5} *\frac{6}{3} *\frac{3}{4} =\frac{36}{60} =\frac{3}{5}$

C)

   √81 + {2.[3+4.(6-2)+(8+3).(5-2)]}

   9 + {2.[3+4.(4)+(11).(3)]}

   9 + {2.[3+16+33]}

   9 + {2.[52]}

   9 + {104}

   113

D)

    $2^{3} +3^{2} .4^{2} +24 \div 2\\8+9*16+12\\8+144+12\\164$

E)

    $\frac{2}{4} +2^{3} -\frac{1}{5} \\\\\frac{1}{2} +8+\frac{1}{5} \\\\\frac{5+80+2}{10} \\\\\frac{87}{10}$

F)

   $\sqrt{49} -\sqrt{25} *2^{4} +5\\7-5*16+5\\7-80+5\\-68$
