x= radical 3 + 2 radical 3 + 3 radical 3
= 6radical 3
y= radical din 98 - radical din 128 + radical din 50
7radical 2 - 6 radical 2 + 5 radical 2 = 6radical 2
z = radical 2 × radical 2 + ( radical 3 )² - 2 radical 5 ×3 radical 5
2+3 - 6×5
2+3 - 30
5 - 30
-25
a) 6radical 3 > 4 radical 2
-25 <4radical 2 < 6 radical 3
Z < Y < X
b) x × radical 3 + | z | - y × radical 2
=6 radical 3 × radical 3 + | - 25 | - 4 radical 2 × radical 2
=6×3 +25 - 8
=43 - 8
= 35
