Answer 2

$\huge\textsf{Hey there!}$

$\mathsf{-11^3 + 8^3 + 3^3}$

$\mathsf{= -11\times -11\times -11 + 8\times8\times8 + 3\times3\times3}$

$\mathsf{= 121\times -11+ 64\times8+9\times3}$

$\mathsf{= -1,331 + 512 + 27}$

$\mathsf{= -819 + 27}$

$\mathsf{= -792}$

$\huge\textsf{Therefore, your answer should be: \boxed{\mathsf{-792}}}\huge\checkmark$

$\huge\textsf{Good luck on your assignment \& enjoy your day!}$
