x³ = 27x = ³√27x = 3
3; -1,5+_1,5iV3.
3. Move on.
3³ = 27....x=3
3^3=273×3×3=27
Very good your explanation ,thank you
Ha, ha, ha...
x^3=27x^3=3^3x=3
Это в уме решается
But you can simply do this in 1 min That is , X³=27 X³=3³ (therefore power is same , so we take it base) X=3.
It takes a little longer for the full answer.
A 0:22 la solution est trouvée. Pourquoi poursuivre, c'est n'importe quoi.
X=3
🤔
The whole point of this video was to prove the fundamental theorem of algebra, which says that a polynomial with a highest power of 3 would have 3 solutions. In this case one real solution (3) and two complex solutions.
