Explications étape par étape
Bonsoir
A = V330 x V66/6
A = V(3 x 11 x 2 x 5) x V(3 x 11 x 2)/6
A = V(3^2 x 11^2 x 5 x 2^2)/6
A = 3 x 2 x 11V5 / 6
A = 11V5
B = 2 x V3 x V21 x 1/6
B = 2 x V3 x V(3 x 7) x 1/6
B = 2 x V(3^2 x 7) x 1/6
B = 2 x 3 x V7 x 1/6
B = 6/6 x V7
B = V7
C = V45 x (-V20)
C = V(9 x 5) x (-V(4 x 5))
C = V(3^2 x 5) x (-V(2^2 x 5))
C = 3V5 x (-2V5)
C = 3 x (-2) x (V5)^2
C = (-6) x 5
C = (-30)
E = -V63 x V14
E = -V(9 x 7) x V(2 x 7)
E = -V(3^2 x 7) x V(2 x 7)
E = -3V7 x V2 x V7
E = -3 x (V7)^2 x V2
E = -3 x 7 x V2
E = -21V2
3eme niveau :
A = 3V3 + 2V3 + 5V3 - 7V3
A = (3 + 2 + 5 - 7)V3
A = (10 - 7)V3
A = 3V3
B = -V11 + 10V11 - 7V11 - 2V11
B = (-1 + 10 - 7 - 2)V11
B = (10 - 10)V11
B = 0 x V11
B = 0
C = 3/2 V7 - 2/3 V7
C = (3/2 - 2/3)V7
C = (9/6 - 4/6)V7
C = 5/6 V7
C = 5V7/6
D = (3 - 5V3) - (6V3 - 7)
D = 3 - 5V3 - 6V3 + 7
D = 3 + 7 - (5 + 6)V3
D = 10 - 11V3
