a) ( -2 )³ ÷ ( -8 ) = -8 ÷ ( -8 ) = 1

b) ( -5 )² ÷ ( -4 -1 ) = ( -5 )² ÷ ( -5 ) = 25 ÷ ( -5 ) = -5

c) ( -5 + 1 )² + ( +4 )² - ( -1 )⁵ = ( -4 )² + 16 - ( - 1 ) = 16 + 16 + 1 = 32 + 1 = 33

d) ( -2 )³ · ( -3 )² - ( - 5 )²· ( -1 )⁴ =  ( - 8 ) . 9 - 25 . 1 =  - 72 - 25 = - 97

e) ( 5 - 10 )² - ( - 3 )² + ( 12 )⁰ = ( - 5 )² - 9 + 1 =  25 - 9 + 1 = 16 + 1 = 17

 

f) ( - 3 )³ · ( - 2 )² + ( - 10 )¹ · ( - 1 )⁵ =  ( - 27 ) . 4 + ( - 10 ) . ( - 1 ) =  - 108 + 10 = -98
