Answer:
The solution is [tex]-23[/tex]
Step-by-step explanation:
We need to solve the expression[tex]x^{3}-2y^{2}-3x^{3}+z^{4}[/tex] at [tex]x=3,y=5, \text{and} \ z=-3[/tex]
Replace 'x' with 3, 'y' with 5 and 'z' with -3 in [tex]x^{3}-2y^{2}-3x^{3}+z^{4}[/tex]
[tex]3^{3}-2(5)^{2}-3(3)^{3}+(-3)^{4}[/tex]
[tex]27-2(25)-3(27)+81[/tex]
[tex]27-50-81+81[/tex]
[tex]-23[/tex]
Therefore, the solution is [tex]-23[/tex]
