Answer 1

a)
= (-2)³ : (-8)
= -2³ : (-8)
= -2³ : 8
= +1

b)
= (-5)² : (-4-1)
= 5² : (4-1)
= 5² : (-5)
= -5² : 5
= -5

c)
= (-5+1)²+(+4)²-(-1)^5
= (-4)²+4²-(-1)^5
= (-4)²+16-(-1)^5
= (-4)²+16-(-1)
= 16+16-(-1)
= 16+16+1
= 33

d)
= (-2)³.(-3)²-(-5)².(-1)⁴
= -2³.3²-25.1
= -8.3²-25.1
= -8.9-25.1
= -72-25
= -97

e)
=(-6)²:(-3)²-(-2+1).(-2)³
= 6²:3²-(-1).(-2³)
= 2²-(-1).(-2³)
= 2²+1.(-2³)
= 2²+(-2³)
= 2²-2³
= -4

f)
= [(-2)⁴+3.(3²-1)]:(-2³+3.2²)
=[16+3(3²-1)]:(-2³+3.2²)
=[16-3(9-1)]:(-2³+3.2²)
=[16+3 .8]:(1.2²)
=[16+24]:(1.2²)
=[16+24]:2²
= 40:2²
= 10
