Here, You have to simplify every number to their simple form and place it on the arrow by approximation:
So, Here is your answers:
Upper Arrows (From Left towards right):
1st = -10√2/3
2nd = -√7
3rd = ∛4
4th = √50
Lower Arrows (From Left towards right):
1st = -√99
2nd = -√17
3rd = ∛9
4th = π
Hope this helps!
