求解 operatorname{low}leqsqrt[13]{frac{sqrt{3}}{3}}

$$\operatorname { low } \leq \sqrt[ 13 ] { \frac { \sqrt { 3 } } { 3 } }$$

求解 w 的值

$$\left\{\begin{matrix}w\geq \frac{3^{\frac{25}{26}}}{3lo}\text{, }&\left(l>0\text{ and }o<0\right)\text{ or }\left(o>0\text{ and }l<0\right)\\w\leq \frac{3^{\frac{25}{26}}}{3lo}\text{, }&\left(l<0\text{ and }o<0\right)\text{ or }\left(l>0\text{ and }o>0\right)\\w\in \mathrm{R}\text{, }&o=0\text{ or }l=0\\w=\frac{3^{\frac{25}{26}}}{3lo}\text{, }&l\neq 0\text{ and }o\neq 0\end{matrix}\right.$$

求解 o 的值

$$\left\{\begin{matrix}o\geq \frac{3^{\frac{25}{26}}}{3lw}\text{, }&\left(l>0\text{ and }w<0\right)\text{ or }\left(w>0\text{ and }l<0\right)\\o\leq \frac{3^{\frac{25}{26}}}{3lw}\text{, }&\left(l<0\text{ and }w<0\right)\text{ or }\left(l>0\text{ and }w>0\right)\\o\in \mathrm{R}\text{, }&w=0\text{ or }l=0\\o=\frac{3^{\frac{25}{26}}}{3lw}\text{, }&l\neq 0\text{ and }w\neq 0\end{matrix}\right.$$
