Bonjour
A = 6V7
B = -4V3
C = 15 - 3V7
D = 5+2V5
E = 3V2-5V2+6V2 = 4V2
F = 8V5 -10V5 +4V(9*9*5) = 8V5-10V5+36V5 = 34V5
J= V147 +3V48 -5V12 -V48 =
J = V(3*49) + 3V(3*16) -5V(3*4) = 7V3 +12V3 - 10V3 = 9V3
K = 5V28 +2V63 +V567 = 5V(7*4) + 2V(7*9) + V(7*81) = 10V7 +6V7 +9V7 = 25V7
6)
Aire grise = (5V21 -V3)(7V3) -(3V2)²
= (5V21)(7V3) - (V3)(7V3) - (9*2)
= 35 V(21 * 3) - 21 - 18
= 35V(9*7) - 39
= 105V7 - 39
