A Nice Math Olympiad Question | You Should Know This Trick.

I just substituted a for x/2 in the beginning then back at the end. Seemed much easier to me.

[@Nazzarari01]

4 complexe roots and 2 real roots

[@terrywhite7190]

Take the sixth root of both sides. X/2 =3. X=6. Not complicated at all.

[@Релайм]

is there any problem to see both got power of 6 so 3=x/2 x=3 times 2 x= 6

[@Gnowop3]

A 10 second answer is: x = 6 cis(2nπ/6) where n = 0,1,2,3,4,5

[@BritishBeachcomber]

Did it in an instant by taking the sixth root of both sides. Trivial.

[@AlexanderSemashkevich]

x=±6

[@johnchapman1903]

Yeah, +/- 6 are the real roots, but seems the complex roots are also required.
