Bonsoir les Amis, aidez moi svp à réduire les expressions : A = 5x3V7 B = 5+3V7 C = 2V5 + 3V5 D = 2V5 - 3V5 E = 3V2 x 5V3 F = 3V2 + 5V3 G = 5V7 - 7V7 H = V(3auc

Bonjour

A = 5x3V7 = 15V7

B = 5+3V7 = 5+ 3V7

C = 2V5 + 3V5 = 5V5

D = 2V5 - 3V5 = -V5

E = 3V2 x 5V3 = 10V6

F = 3V2 + 5V3 = 3V2 + 5V3

G = 5V7 - 7V7 = -2V7

H = V(3aucarré +2aucarré)

= 3+2 = 5

I = V8 - 2V2 = V4*2 -2V2 = 2V2 -2V2 = 0

J = V8 x (-2V2) = -2V16 = -2*4 = -8

K = (2V5) / V15 = 2 /V3

L = (8V6) / (2V3) = 4V2

Bonsoir,

A = 5x3√7

A= 15√7

B = 5+3√7

B=  5+ 3√7

C= 2√5 + 3√5

C= 5√5

D= 2√5 - 3√5

D= -√5

E = 3√2 x 5√3 = 15√6

F = 3√2 + 5√3

F= 3√2 + 5√3

G = 5√7 - 7√7

G= -2√7

H =√(3² +2²)

H= √3²+√2²

H= 3+2

H= 5

I = √8 - 2√2

I=  √4x√2 -2√2

I=  2√2 -2√2

I= 0

J = √8 (-2√2)

J= -2√16

J= -2√4x√4

J= -2(2)(2)

J= - 8

K = (2v5) /√15

K= 2√5 / √3 x √5

K = 2 /√3

L = (8√6) / (2√3)

L= 8 √3 x √2 / 2√3

L= 8 √ 2/ 2

L = 4√2
