Question

02. Determine o valor de cada expressão:
a) 2 + (3 - [1 + (2 - 5 + 4)] + 8) =
b) (2 -[3.4 + 2-2.(3-1)]] + 1 =​

Answer 1

Resposta:

A) 2+ (3-[ 1+(2-5+4)]+8)

2+(3-[1+(3+4)]+8)

2+(3-[1+7]+8)

2+(3-8+8)

2+(5+8)

2+13 = 15

B) (2-[3•4+2-2•(3-1])+1

(2-[3•4+2-2•2])+1

(2-[13+2-2•2])+1

(2-[13+2-4])+1

(2-[15-4])+1

(2-11)+1

9+1 = 10
