a) 2 - 4a = 2 - 4 * (- 5) = 2 + 20 = 22
b) 1 1/2b + 3/4 = 1 1/2 * 1/2 + 3/4 = 3/2 * 1/2 + 3/4 = 3/4 + 3/4 =
= 6/4 = 1 2/4 = 1 1/2
c) e³ + e² + e = (- 4)³ + (- 4)² + (- 4) = - 64 + 16 - 4 = - 52
d) 5x - 2y = 5 * (- 1/2) - 2 * (- 1 1/4) = - 5/2 - 2 * (-5/4) = - 5/2 + 10/4 =
= - 10/4 + 10/4 = 0
e) 0,25(f - 1/2) = 0,25(- 1/2 - 1/2) = 0,25 * ( - 1) = - 0,25
