Calculate the following limit:
lim
I need find this limit without l'Hospital or Taylor series.
Wolfram alpha gives \frac{1}{2}
My try is:
Let: a=\sqrt{1+x^{2}} and b=\sqrt[3]{1+x^{3}}
And we know that:
a-b=\frac{a^{3}-b^{3}}{a^{2}+b^{2}+ab}
But after applied this I find again the problems 0.+\infty indeterminate
