Simplify the algebraic expression $x\cdot x\left(x^2+1\right)$

$2\frac{2}{3}\cdot k\cdot b\cdot l\cdot k\cdot b\cdot l$

$\sqrt{3a^2} b^3\sqrt{6a^5}\cdot b$

$3x^5\cdot 2 x^2$

$e e e d\cdot i\cdot f\cdot f\cdot r\cdot n\cdot t\cdot i\cdot a\cdot t\cdot \ln\left(2+x^2\right)$

$e t\cdot x\cdot t\cdot\left(\left(q-3\right)\left(q-4\right)+\left(q-3\right)\left(q+4\right)\right)$

$-2x^2\cdot\frac{1}{2} x^{\left(-1\right)\cdot\frac{1}{2}}$

$\sqrt{\sqrt{3y^3}}\left(\sqrt{^{3y^3}}\right)^{\frac{1}{3}}$
