Explications étape par étape
Bonjour
Simplifier :
A = 2V20 - V45 + V125
A = 2V(2^2 x 5) - V(3^2 x 5) + V(5^2 x 5)
A = 2 x 2V5 - 3V5 + 5V5
A = 4V5 + 2V5
A = 6V5
B = 7V3 - 3V48 + 5V12
B = 7V3 - 3V(4^2 x 3) + 5V(2^2 x 3)
B = 7V3 - 3 x 4V3 + 5 x 2V3
B = 7V3 - 12V3 + 10V3
B = 17V3 - 12V3
B = 5V3
C = V96 + 2V6 - 2V24 - 3V54
C = V(4^2 x 6) + 2V6 - 2V(2^2 x 6) - 3V(3^2 x 6)
C = 4V6 + 2V6 - 2 x 2V6 - 3 x 3V6
C = 6V6 - 4V6 - 9V6
C = 6V6 - 13V6
C = (-7V6)
D = 2V32 - 3V50 + 6V8
D = 2V(4^2 x 2) - 3V(5^2 x 2) + 6V(2^2 x 2)
D = 2 x 4V2 - 3 x 5V2 + 6 x 2V2
D = 8V2 - 15V2 + 12V2
D = 20V2 - 15V2
D = 5V2
