Question

resolva as expressões numéricas:
25+{[17+(5-3)]-(1-4)} =
-2-{4+[10-(-2-3)]+2+(-5-7)} =
-5{+5-[-5-(-11+10)]+3} =
16+[-2+(4+3)]+10 =

Answer 1

Resposta:

A) 47

B) -11

C) 7

D) 31

Explicação passo-a-passo:

A) 25+{[17+(5-3)]-(-1-4)}=

25+{[17+2]-(-3)}=

25+{19+3}=

25+22=

47

B) -2-{4+[10-(-2-3)]+2+(-5-7)}=

-2-{4+[10-(-5)]+2+(-12)}=

-2-{4+[10+5]+2-12}=

-2-{4+15-10}=

-2-{+9}=

-2-9=

-11

C) -5{+5-[-5-(-11+10)]+3}=

-5{+5-[-5-(-1)]+3}=

-5{+5-[-5+1]+3}=

-5{+5-[-4]+3}=

-5{+5+4+3}=

-5+12=

+7

D) 16+[-2+(4+3)]+10=

16+[-2+7]+10=

16+5+10=

+31

espero ter ajudado, qualquer dúvida me fala
