The only realistic way is to use a calculator. If you want to find the 9th root of x find x(1/9) ie x to the power of 1/9.
You could try cube root of a cube root, but unless the number is a ninth power of an integer (or of the ratio of two small integers AND your mental maths is good), that will not get you very far.
You could try logs but in all likelihood, the only place you will find logs are using a calculator. And if you are using a calculator, you may as well use the first option.
