Find the limit of (lnx)³/x as x approaches infinity.
now when i take an arbitrary very big number and try calculating the limit with a calculator, it gives 0.
on the other hand i thought about this:
g(x)=x³
lim(x goes to + inf) g(x)=+inf
lim(x goes to +inf) g(x)/x = +inf
lim(x goes to +inf) lnx=+inf
then
lim(x goes to +inf) g(lnx)/x=+inf
which is obviously
