Answer: [tex]\sqrt[5]{y}[/tex]
I realize its probably not the largest readable font. If you are having trouble reading it, it is the square root of y; however, there is a tiny little 5 in the upper left corner to indicate a fifth root. So you would read it out as "the fifth root of y"
The rule I'm using is
[tex]x^{1/n} = \sqrt[n]{x}[/tex]
and the more general rule we could use is
[tex]x^{m/n} = \sqrt[n]{x^m}[/tex]
where m = 1. This rule helps convert from rational exponent form (aka fractional exponents) to radical form.
