A share has value $y, x days after launch, given by y=x^(1/3),find the value of share 1000days after launching and use 'small changes' to find the value 1000 days after launching

The first part of that is just arithmetic: .

I don't know what the second part of that means. "Small change" from what? Is it possible that the second part asked for the value after, say, 1001 days or 1008 days?

no, 1001 is a big change it is something like 1000.1 days so say the small change can be
1000.1-1000=0.1
small change in y=dy/dx*small change in x=dy/dx*0.01
