Verified answer

Bonsoir,

B = (17 - 7 + 3) / [6 - (12 - 2 x 4²)]

B = 13 / [6 - (12 - 2 x 16)]

B = 12 / [6 - (12 - 32)]

B = 12 / [6 - (- 20)]

B = 12 / (6 + 20)

B = 12/26

B = (2 x 6) / (2 x 13)

B = 6/13.

Réponse :

Bonjour,

B = (17-7+3)/(6-(12-2*4²))

B = 13/(6-(12-2*16))

B = 13/(6-(12-32))

B = 13/(6-12+32)

B = 13/26

B = (13*1)/(13*2)

B = 1/2

B = 0,5
