Question

find the value of x, x=(-8)^3+12(8)^2-5

Answer 1

$= > x = {( - 8)}^{3} + 12( {8})^{2} - 5 \\ \\ = > x = - 512 + 12 \times 64 - 5 \\ \\ = > x = - 517 + 768 \\ \\ = > x = 251$

Answer 2

$\textbf{Answer :}$

$\textbf{Now,}$

$ x = (-8)^3 + 12 (8)^2 - 5 $

$ = ( - 512) + 12 (64) - 5, $

since $ (-8)^3 = - 512 $ and $ 8^2 = 64 $

$ = - 512 + 768 - 5 $

$ = 251 $

$\textbf{Therefore, the value of x is 251}$.
