Answer 1

a) (-45)³*(1/15)³+ 25²:(-5)² = (-3)³ + (-5)² = -27+25 = -2

b) (1/42)³ :(-1/21)³- 100³*(-1/10³ = (-1/2)³ - (-10)³ = (-1/8)-(-1000) = -1/8+1000 = 999 7/8

c) (1,2³: 12³-(0,6)⁵*(-1 i 2/3)⁵ = 0,1³-(6/10)⁵*(-5/3)⁵ = 0,1³ - (-1)⁵ = 0,001-(-1) = 0,001+1 = 1,001

d) (-1 i 1/3)²¹* (0,75)²¹-(0,5)⁰: 2⁰ = (-4/3)²¹ * (3/4)²¹ - 0,25⁰ = (-1)²¹ - 1 = -1-1 = -2
