[tex]\huge\textsf{Hey there!}[/tex]
[tex]\mathsf{-11^3 + 8^3 + 3^3}[/tex]
[tex]\mathsf{= -11\times -11\times -11 + 8\times8\times8 + 3\times3\times3}[/tex]
[tex]\mathsf{= 121\times -11+ 64\times8+9\times3}[/tex]
[tex]\mathsf{= -1,331 + 512 + 27}[/tex]
[tex]\mathsf{= -819 + 27}[/tex]
[tex]\mathsf{= -792}[/tex]
[tex]\huge\textsf{Therefore, your answer should be: \boxed{\mathsf{-792}}}\huge\checkmark[/tex]
