Question 707056
Not important unless you need x to be a certain value.  Only two meaningful options for placing parentheses, at best.


{{{28-(3x^3+4)=79}}} will make {{{x = root(3,(-55/3))}}} .


{{{(28-3x^3)+4=28-3x^3+4=79}}} will make {{{x = root(3,(-47/3))}}}.


Nothing more.  Only one option has any effect on meaning of the expression.
