Answer 2

Answer:

2 , 4, 76/81 , 15/16

Step-by-step explanation:

=1×1(3-2×1+1×1)

=1(3-2+1)

=2

-1×-1(3-2×-1+-1×-1)

1(3+2-1)

1(5-1)

=4

2/3×2/3 (3-2×2/3+2/3×2/3)

4/9(3-4/3+4/9)

4/9(27-12+4/9)

4/9(15+4/9)

4/9(19/9)

=76/81

-1/2×-1/2 (3-2×-1/2+-1/2×-1/2)

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

1/4(3+1-1/4)

1/4(12+4-1/4)

1/4(15/4)

=15/16
