"Root", as in solution? There is no third root of that equation. The darned thing is a quadratic, with precisely two roots: plus or minus 3.

In general, a polynomial equation of order n can have at most n distinct roots. Fundamental theorem of Algebra.

do you mean find the answer then take the 3rd root? because taking the third root of both sides will not change the answer
x^2=9
x=+-3

so (3)^(1/3)=1.44
(-3)^(1/3)=-1.44
