{\large{\red{\mapsto{\maltese{\underline{\green{\boxed{\blue{\underbrace{\overbrace{\pink{\pmb{\bf{Answer:}}}}}}}}}}}}}}


\blue{ {x}^(2) - 8 = 8}


\purple{ {x}^(2) - 8 + 8 = 8 + 8}


\red{ {x}^(2) = 16}


\green{ \sqrt{ {x}^(2) } = √(16) }


\pink{x = 4}

{x}^(2) - 8 = 8 \\

x^2 - 8 + 8 = 8 + 8

x^2 = 16

x = √16

x = 4
