Bonsoir Math exercice 5 s’il vous plaît

Réponse:

À = 81/9*5-1. 81/9 = 9/1=9

= 9*5-1

= 45-1

= 44

B =45/2*3-1. 2*3-1 = 6-1 = 5

= 45/5

= 9

C= 27/2*3 - 1

= 27/6 - 1/1

= 4,5 - 1

= 3,5

D = 17 - 5/3 + 2

= 12 /3 +2/1

= 12 +2 / 3+1

= 14/4

= 3,5

E = 7* 15*4/3-2+2*8

= 7*60/1 + 2*8

= 7*60+16

= 436

F = 13+5/13-(2*4)

= 18/13-8

=18/5

= 3,6
