a) -14 radical 2
b) 11 radical 3
Explicație pas cu pas:
a) 3 radical 8 + 5 radical 18 - 7 radical 50 = 3 * 2 radical 2 + 5 * 3 radical 2 - 7 * 5 radical 2 = 6 radical 2 + 15 radical 2 - 35 radical 2 = -14 radical 2
b) 2 radical 27 - 7 radical 3 + 6 radical 12 = 2 * 3 radical 3 - 7 radical 3 + 6 * 2 radical 3 = 6 radical 3 - 7 radical 3 + 12 radical 3 = 11 radical 3
