Answer:
Statement says that x varies inversely with ³√y
According to the above problem, we get
x=k/³√y, where k is a constant
Now, by putting x=3 when y=64
we have to find the value of k
3=k/³√64
3=k/4
k=3×4
k=12
Now, by putting the value of k
we have a find the value of x when y=1000
x=12/³√1000
x=12/10
x=1.2
★ x=1.2 is the right answer.
