I love mathematics but unfortunately I can't say the same about it.

 8 Is $\lim_{n\rightarrow\infty}\sin\left(\pi\sqrt[3]{n^{3}+1}\right)$ exist? 6 $x,y,z$ are positive real numbers and $x+y+z=1$ $\implies$ $\bigg(1+\dfrac 1x\bigg)\bigg(1+\dfrac 1y \bigg)\bigg(1+\dfrac 1z \bigg)\ge 64$? 6 Test the convergence of a series 6 Differential inequality implies inequality for points at distance pi. 4 $\lim \limits_{\left(x,\:y,\:z\right)\to \left(0,\:0,\:0\right)}\left(\frac{xyz}{\sqrt{x^2+y^2+z^2}}\right)$
