Formula

Solve the cubic equation

Answer

$a ^{ 3 } = 9$

$a = \sqrt[ 3 ]{ 9 }$

Solve the cubic equation

$\color{#FF6800}{ a } ^ { \color{#FF6800}{ 3 } } = \color{#FF6800}{ 9 }$

$ $ Do the cube root on both sides of the equation $ $

$\color{#FF6800}{ a } = \sqrt[ \color{#FF6800}{ 3 } ]{ \color{#FF6800}{ 9 } }$
