When I try to render the figure with mathematical expression(exactly n-th root), I got this message:

Expected \sqrt{value}, found ‘[’ (at char 5), (line:1, col:6).

My code is plt.text(0.5, 0.5, `'$\sqrt[n]{5}$'`

). However, if I replace` '$\sqrt[n]{5}$'`

with `'$\sqrt[3]{5}$'`

, it can run successfully. why their results are different? Thank you!

You cannot do that in 3.3.4; support for non-integer roots was added in 3.4.0.
