Question
reduire
G = 7 racine carré 6 + racine carré 24
H = racine carré 98 - 9 racine carré 2
I = 4 racine carré 6 + 32 racine carré 28
J = racine carré 5 - 2 racine carré 30 + 3 racine carré 45
K = 4 racine carré 10 + 5 racine carré 40 - 2 racine carré 160
merci de m'aider

1. Réponse nonotata
G = 7 racine carré 6 + racine carré 24
= 7V6 +V4x6
= 7V6+2V6
=9V6
H = racine carré 98 - 9 racine carré 2
h = V49x2 -9V2 = 7V2-9V2 = -2V2
I = 4 racine carré 6 + 32 racine carré 28
= 4V6 +32V4x6
=4V6+64V6
=68V6
J = racine carré 5 - 2 racine carré 30 + 3 racine carré 45 ( est tu sur du -2 V30??)
= V5-2V30-3V9x5
= V5-2V30-9V5
= -2V30-9V5
K = 4 racine carré 10 + 5 racine carré 40 - 2 racine carré 160
k = 4V10+5V4x10 -2V16x10
k = 4V10 + 10V10-8V10
= 6V10
