Answer 1

a) {36 + [49 - (710 - 694)]}

{36 + [49 - 16]}

{36 + 33}

69

b) √81 + 36 × 2³

9 + 36 × 8

9 + 288

297

c) 25 - 32 × √64

25 - 32 × 8

25 - 256

-231

d) - {49 + [√1024 - (3 + 11)]}

- {49 + [32 - 14]}

- {49 + 18}

-67

e) 1368 - 8 × 32 + √676

1368 - 256 + 26

1394 - 256

1138

f) 2/3 + 7² - √169

2/3 + 49 - 13

2/3 + 36 ---> mmc(36,3) = 36, dps 108

2+108/3

110/3 = 36,6

g) 13 + 5 - 7/3

18 - 7/3

54-7/3

47/3 = 15,6

h) -50 + {36 - [87 - (5 × 4) × 10] × (-2) + 100}

-50 + {36 - [87 - 20 × 10] × (+2) + 100}

-50 + {36 - [87 - 200] × (-2) + 100}

-50 + {36 - [-113] × (-2) + 100}

-50 + {36 + 113 × (-2) + 100}

-50 + {36 - 226 + 100}

-50 + {-90}

-50 - 90

-140
