Convert all of them to meters.
1 km = 1000 meters
6 * 1000 = 6000
6 km = 6000 m
1 cm = 0.01 m
600 * 0.01 = 6
600 cm = 6 m
1 mm = 0.001 m
6000 * 0.001 = 6 m
So we have:
6000 m, 60 m, 6 m, and 6 m.
So 6 kilometers is the greatest.

<u>Step-by-step explanation:</u>

Step-by-step explanation:
Consider x⅓ =a
then the following expression can be written as
a²+a-2
a²+2a-a-2
a(a+2)-1(a+2)
(a+2)(a-1)
a= -2 or, a= 1
Putting the value of a
x⅓ = -2 and, x⅓ =1
Answer:
The Answer is X= 17.1 in.
