Bonjour
Explications étape par étape :
A =2× (5+4)² = 2 X 9² = 2 X 81 = 162
B=16/(3-1)² = 16 / 2² = 16/4 = 4
C = 2× (1-5)³ = 2 X -4³ = 2 X -64 = - 128
D = [2+2 × (-3)]⁴ = ( 2 + 2 X -3)⁴ = (2 -6)⁴ = -4⁴ = + 512
E = [2+(-2)⁴× 3] × (3³-1)
E = 2 + 16 X 3 X (27 -1)
E = 2 + 48 X 26
E = 2 + 1 248
E = 1 250
F = 3× (1-3)⁵-2²× (3+2)
F = 3 X -4⁵ + 4 X 5
F = 3 X - 1 064
F = - 3 192
