Your formatting is ambiguous. Are the exponents all fractions? Does, for instance, "1/3x^-2/3" mean:
. . . . .\(\displaystyle \large{\frac{1}{(3x)^{(-\frac{2}{3})}}}\)
...or:
. . . . .\(\displaystyle \large{\frac{\frac{1}{3}x^{-2}}{3}}\)
...or something else?
Please reply with clarification. Thank you.
