3) 18 + {5 + [43 – 2 (42 + √64 )] – 7} + 33

Answer 1

Respuesta:

3) 18 + {5 + [43 – 2 (42 + √64 )] – 7} + 33 = -8

Explicación paso a paso:  

18 + {5 + [43 – 2 (42 + √64 )] – 7} + 33

18 + {5 + [43 – 2 (42 + 8 )] – 7} + 33

18 + {5 + [43 – 2 (50)] – 7} + 33

18 + {5 + [43 – 100] – 7} + 33

18 + {5 + [-57] – 7} + 33

18 + {-52 – 7} + 33

18 + {-59} + 33

18 + {-26}

-8
