Answer 1

a) 3•[-9+4•(-4+5)]:(+9-2-12)=
3•(-9+4•1):(-5)=
3•(-5):(-5)=3
b) (-2)•[(-12):(-4+9-2)-(3-5)]=
(-2)•[(-12):3+2]=
(-2)•[(-4)+2]=
(-2)•(-2)=4
c) [(-3)⁰+4•(-2)]⁶:(-49)²=
(1-8)⁶:(-7²)²=
(-7)⁶:(-7)⁴=(-7)²=49
d){[20:(-4)]¹⁰:25⁴-36}•(-4)²-(-3²)=
[(-5)¹⁰:(5²)⁴-36]•(-4)²-(-3²)=
[(-5)¹⁰:5⁸-36]•(-4)²-(-3²)=
(5²-36)•16+9=
(-11)•16+9=
(-176)+9=(-167)
e){(-4)•[(-4)²-9]-(7-11)}•(-2)-10•(-2)⁴=
[(-4)•(16-9)+4]•(-2)-160=
[(-4)•7+4]•(-2)-160=
(-24)•(-2)-160=
48-160=(-112)
f){12⁰-[(-5)²+(-3²)-(-2)⁵]:(-8⁰)+9}•(-2³)=
{1-[(25-9+32)]:1+9}•(-8)=
(1-48:1+9)•(-8)=
(1-48+9)•(-8)=
(-38)•(-8)=304
