How do you input an answer in the practice problems or quiz that involve other roots beside square root and cube root ?

For example, the question say to rewrite x^(5/7) as a radical but there are no button option that would allow a student to do that. The only button available are square root and cube root. By the way, I am using Windows 10 and Firefox as my browser if that make any difference.

Sheila,

Since no one responded, I google searched and found out that you can input other roots. Just click on the cube root button, then change the index of the radical "3" to what ever number you want.

I know, it is very unintuitive and I wish Khan Academy either add another button and label it "nth root" or replace the cube root button with just the "nth root" button.

Hope that helps.
