Question

Calcule as expressões:
$(4 + 2(10 - (5 + 1) - 3 {)}^{2}$
$76 - (4 + (30 + 6) \times (2 + 5) \times 2) + 2$
$54 - 3 \times ((7 + 6 + 2) - (4 \times 3 - 5)$

$(50 - (20 \div 2) \times 3) + (15 + 5 \times (1 + 3 {}^{2}))$
$(10 - (90 \div (17 + 28)) {}^{z}$
$5 + (43 + (32 - 1) + 15 \times 3) + (6 - 2) {}^{2}$

Answer 1

Ola!!

A)

(4+2(10-(5+1)-3))²

(4+2(10-6-3))²

(4+2•1)²

(4+2)²

6²=36

B)

76-(4+(30+6)•(2+5)•2)+2

76-(4+36•7•2)+2

76-(4+36•14)+2

76-(4+504)+2

76-508+2

-430+2

-430

C)

54-3•((7+6+1)-(4•3-5))

54-3•(15-7)

54-3•8

54-24

30

D)

(50-(20÷2)•3)+(15+5•(1+3²))

(50-10•3)+(15+5•10)

(50-30)+(15+50)

20+65

85

E)

(10-(90÷(17+28)))^z

(10-(90÷45))^z

(10-2)^z

8^z

F)

5+(43+(32-1)+15•3)+(6-2)²

5+(43+31+45)+4²

5+119+16

140
