a) ( – 4/3 )² – 1 =
16/9 – 1 =
7/9
b) 2/3 + ( – 1/3 )³ =
2/3 . ( – ( 1/3 )³ ) =
– 2/3 . 1/27 =
– 2/81
c) 3/2 + ( 1/2 )² – 8 =
3/2 + 1/4 – 8 =
– 25/4
d) 1 + 3/5 + ( – 1/2 )³ =
1 + 3/5 – 1/8 =
59/30
e) ( 1 + 1/2 )³ – 1/4 =
( 3/2 )³ – 1/4 =
27/8 – 1/4 =
25/8
f) – 2/3 + 1/2 – ( – 1/2 )² =
– 2/3 + 1/2 – 1/4 =
– 5/24
g) 4 ( – 1/2 )² – ( – 1/3 ) =
4 . ( – 1/2 )² + 1/3 =
4 . 1/4 + 1/3 =
1 + 1/3 =
4/3
h) ( 1 – 1/2 )² + ( – 1 + 1/2 )³ =
( 1/2 )² + ( – 1/2 )³ =
1/4 – 1/8 =
1/8
Espero ter te ajudado mesmo respondendo a questão 1!
