a³ + b³ + c³, if a = 2 , b = -2, c = 1 find the value of the expression

${ \color{aqua}{ \underbrace{ \underline{ \color{lime}{ \mathbb{✯꧁ ⋆᭄ SoLuTiOn⋆᭄꧂✯ }}}}}}$

$a³ + b³ + c³$

$a = 2 \\ b = - 2 \\ c = 1$

$substitute \: the \: values$

$= {(2)}^{3} + { (- 2)}^{3} + {(1)}^{3}$

$= 8 + ( - 8) + 1$

$= 8 - 8 + 1$

$= 1$
