Answer 1

Resposta:

A)

$[(21/7 + 2 /1 ) + 4 ] + 6 * ( 14 / 2 + 3 - 5) = \\\\[3+2+4]+6*7-5 =\\\\9 + 42 - 5 =\\\\9+ 37 =\\\\46$

$B) (100-7/4)/(40-8/2) =\\\\100-1,75/40-4 =\\\\98,25 / 36 = \\\\2,729166666666667$

$C) 120/{[(3*5)-4+ (8*3+5)]}=\\\\120/{[15 - 4 + 24 + 5]} =\\\\120/11+29=\\\\120/30=4$

$D) (20+21/3) * ( 36/3-4)=\\\\20 + 7 * 12-4=\\\\27*8=216$

$E) {[(40-3)/2+(8*5)/4]+15/3} =\\\\(37/2+40/4)+5 =\\\\18,5+10+5=\\\\28,5+5=\\\\33,5$

98.

$A) 30-40/(8-3)/2 = \\\\-10 / 5 / 2 =\\\\-2/2 =-1$

$B) [100-413*(20-5*4)+25]/5 =\\\\(-313 * 0 + 25 )/5=\\\\0 +25 /5 =5$

$D) 27+[14+3*(100/(18-4*2) +7]/13 = \\\\27+[11 * (100 / 10 ) +7]/13 = \\\\27+ (11 * 10 +7 ) /13 =\\\\27 + 117 / 13= \\\\27 + 9 = 36$

Explicação passo-a-passo:

a letra C da 98 não consequi colocar
