you can factor out an x^(1/3), and then the solution is clear
you have (x^(1/3) - x^(1/2))
you want to factor out the smaller power, which is 1/3
so what do you get when you factor out x^(1/3)
yea
and so what happens when x goes to infinity
thats not indeterminate, its just -inf
the answer is negative infinity
you dont eliminate it
if you have a really big positive number times a really big negative number, the answer is a really big negative number
if you have a really big number minus a really big number, the answer will be different depending on which number is bigger
inf * inf is not indeterminate, inf - inf is
It's not
