помогите пожалуйста срочно

Answer 1

надеюсь разберешься!!!!!!

Answer 2

а)
(-1)² - 5/16 = 1 - 5/16 = 16/16 - 5/16 = 11/16

(-3/4)² - 5/16 = 9/16 - 5/16 = 4/16 = 1/4

б)
9 - (-1)³ = 9 - (-1) = 9 + 1 = 10

9 - (-0,3)³ = 9 - (-0,027) = 9 + 0,027 = 9,027

9 - (4/3)³ = 9 - 64/27 = 243/27 - 64/27 = 179/27 = 6 целых 17/27
