If #x=3^(1/3)+3^(-1/3)# then what is the value of #3x^3-9x=10#?
Let's solve each term on the RHS of the first equation:
Plugging in that value for
That's the extent of my knowledge. I'll have someone check and add on to this answer.
Of course it's answer will be zero if the equation has a solution
Substitute the value of
