Explications étape par étape
Bonsoir
Écrire sous la forme la plus simple :
[tex]A = \sqrt{2} * \sqrt{8}[/tex]
[tex]A = \sqrt{2} * \sqrt{2^{3}}[/tex]
[tex]A = \sqrt{2^{2+3}}[/tex]
[tex]A = \sqrt{2^{5}}[/tex]
[tex]A = 2 * 2 \sqrt{2}[/tex]
[tex]A = 4\sqrt{2}[/tex]
B = V10 x V100
B = V10 x V(10^2)
B = V10 x 10
B = 10V10
C = V3 x V12
C = V3 x V(2^2 x 3)
C = V3 x 2V3
C = 2 x (V3)^2
C = 2 x 3
C = 6
D = V80 x V8
D = V(4^2 x 5) x V(2^2 x 2)
D = 4V5 x 2V2
D = 4 x 2 x V(5 x 2)
D = 8V10
E = V75 x V32
E = V(5^2 x 3) x V(4^2 x 2)
E = 5V3 x 4V2
E = 5 x 4 x V(3 x 2)
E = 20V6
F = V99 x V165
F = V(3^2 x 11) x V(3 x 5 x 11)
F = 3V11 x V(15 x 11)
F = 3 x V(11^2 x 15)
F = 3 x 11 x V15
F = 33V15
G = V27 x V15
G = V(3^2 x 3) x V(3 x 5)
G = 3V3 x V(3 x 5)
G = 3 x (V3)^2 x V5
G = 3 x 3 x V5
G = 9V5
E = V63 x V14
E = V(3^2 x 7) x V(2 x 7)
E = 3V7 x V(2 x 7)
E = 3 x (V7)^2 x V2
E = 3 x 7 x V2
E = 21V2
