$$\pi(n)=\phi\left(n,\pi\left(n^\frac{1}{3}\right)\right)-\pi\left (n^\frac{1}{3} \right ) + 1 - \sum_{p\in \left(n^\frac{1}{3},n^\frac{1}{2} \right] } \pi \left (\frac{n}{p} \right )-\pi(p)+1 $$

$\displaystyle\sum_{n \geq 0}{(x+y)^n\frac{u^n}{n!}}=\sum_{k \geq 0}\frac{x}{x-kz}(x-kz)^k\frac{u^k}{k!}\sum_{l \geq 0}\frac{(y+kz)^l}{l!}u^l$
