A = 5 - 2³ + 12 x 2⁻²
= 5 - 8 + 12 x 1/2²
= -3 + 12 x 1/4
= -3 + 12x1/4
= -3 + 3
= 0
B = (5 - 2)³ + 12 x 2⁻²
= 3³ + 12x1/4
= 27 + 3
= 30
C = (5 - 2³ + 12) x 2⁻²
= (5 - 8 + 12) x 1/4
= 9 x 1/4
= 9/4
= 2,25
D = 5 - (2³ + 12) x 2⁻²
= 5 - (8 + 12) x 1/4
= 5 - 20x1/4
= 5 - 20/4
= 5 - 5
= 0
E = 5 - (2³ + 12x2⁻²)
= 5 - (8 + 12x1/4)
