Question

Faça os Cálculos a)-7/2+(-7)/2​

Answer 1

$\frac{7}{2} + \frac{-7}{2}$

$= \frac{7+-7}{2}$

$= \frac{0}{2}$

$= 0$

b) -2³ - 30 + 1

= −8 −30 + 1

= −38 + 1

= −37

c)(-2/3)³ + 1

= -8/27 + 1

= 19/27

d)-5² + (-3)² - 10

= −25 + (−3)²−10

= −25 + 9 −10

= −16 −10

= −26

e)3² + 3 -²

= 9 + 3 -²

= 9 + 1/9

= 82/9

f)5º - (-1) - (-1/2)²

= 1 + 1 - (1/4)

2 - 1/4 = 7/4

g)(1 - 1/2)⁴ + (1 + 1/2) -¹

(1/2)^4 + (3/2)^-1=

1/16 +2/3=

3+32/48=

34/48= {simplifica por 2} Logo : 17/24
