Question

a){ [ ( 5² - 3 ) + ( 7 + 25) – 2 ] + 5 } - 2 . 6 =
b) 50 - [ 3² . 4 - ( 3 . 5 - 2³ ) ] =
c) {- 28 + [ 4² - ( 36 : 9 - 2) - 100] + 35} =
d) 5³ - { ( -6)² + [ -2 . 7 – 6² + ( -4)] : 3} =

Answer 1

Resposta:

a)

{[(5²-3)+(7+25)-2]+5}-2.6

{[(25-3)+32-2]-5{-12

{[22+30]+5-12

{52+5}-12

57-12

45

b)

50-[3².4-(3.5-2³)]

50-[9.4-(3.5-8)]

50-[36-(15-8)]

50-[36-7]

50-29

21

c)

{-28+[4²-(36:9-2)-100]+35}

-28+[16-(4-2)-100]+3

-28+[16-2-100]+35

-28-86-35

-79

d)

5³-{(-6)²+[-2.7-6²+(-4)]:3}

125-{-216+[-2.7-36+(-4)]:3}

125-{-216+[-14-36+(-4)]:3}

125-{-216-54:3}

125+279
