Answer 1

a) (-7)² + (-1)² = 49 + 1 = 50

 

b) (-6-4)² - 2² = (-10)² - 4 = 100 – 4 = 96

 

c) (-8)² - (-3)³ = 64 – (-27) = 64 + 27 = 91

 

d) (6-10+12)² - (-4+5)³ = 8²  - 1³ = 64 – 1 = 63

 

e) ( - 1/2)² - (4/5)⁰ = ¼ - 1 =  -3/4

 

f) ( 1 1/2 )³ - (-1/2)² = (3/2)³ - (1/2)² = 27/8 – ¼ = 27/8 – 2/8 = 25/8 = 3  1/8

 

g) (-1,2)² - (-1,44)¹ = 1,44 + 1,44 = 2,88

 

h) (-0,1)³ + (-2,3)² =  - 0,001 + 5,29 = 5,289
