Question

1 resuelve las siguientes operaciones combinadas ​

Answer 1

Respuesta:

a) (5 • 6 + 3) + 7 • 8

= (30 + 3) + 7 • 8

= 33 + 7 • 8

= 33 + 56

= 1.848

b) 64 ÷ 8 • 3 - (48 ÷ 2 + 1 - 1)

= 64 ÷ 8 • 3 - (24 + 1 - 1)

= 8 • 3 - (24 + 1 - 1)

= 24 - (24 + 1 - 1)

= 24 - (25 - 1)

= 24 - 24

= 0

c) (5 + (8 • 3 ÷ 6) - 7)

= (5 + (24 ÷ 6) - 7)

= (5 + 4 - 7)

= 9 - 7

= 2

d) 17 - 10 + {14 - 3 + (5 • 8 ÷ 20)}

= 17 - 10 + {14 - 3 + (40 ÷ 20)}

= 17 - 10 + {14 - 3 + 20}

= 17 - 10 + {11 + 20}

= 17 - 10 + 31

= 7 + 31

= 38

e) {55 ÷ 11 + 66 ÷ 11 + (77 ÷ 11 - 11)}

= {55 ÷ 11 + 66 ÷ 11 + (7 - 11)}

= {55 ÷ 11 + 66 ÷ 11 + (-4)}

= {5 + 66 ÷ 11 + (-4)}

= {5 + 6 + (-4)}

= 11 + (-4)

= 7

f) [44 ÷ 11 + 7] + [88 ÷ 11 • 5]

= [4 + 7] + [88 ÷ 11 • 5]

= [4 + 7] + [8 • 5]

= 11 + 40

= 51

g) 40 + [25 - (3 + 2)]

= 40 + [25 - 5]

= 40 + 20

= 60

h) 60 + [(4 + 2) - 5]

= 60 + [6 - 5]

= 60 + 1

= 61

______________________________________________________

a) 450 - {6 + [4 - (3 - 1)]}

= 450 - {6 + [4 - 2]}

= 450 - {6 + 2}

= 450 - 8

= 458

b) 520 + {8 - 3 + [9 - (4 + 2 - 1)]}

= 520 + {8 - 3 + [9 - (6 - 1)]}

= 520 + {8 - 3 + [9 - 5]}

= 520 + {8 - 3 + 4}

= 520 + {5 + 4}

= 520 + 9

= 529

c) (150 - 5) - [14 + (9 - 6 + 3)]

= 145 - [14 + (9 - 6 + 3)]

= 145 - [14 + (3 + 3)]

= 145 - [14 + 6]

= 145 - 20

= 165
