Question

Evaluate the following expression using the values given:

Answer 1

The result of this question is -23

Answer 2

Answer:

The solution is $-23$

Step-by-step explanation:

We need to solve the expression$x^{3}-2y^{2}-3x^{3}+z^{4}$ at $x=3,y=5, \text{and} \ z=-3$

Replace 'x' with 3, 'y' with 5 and 'z' with -3 in $x^{3}-2y^{2}-3x^{3}+z^{4}$

$3^{3}-2(5)^{2}-3(3)^{3}+(-3)^{4}$

$27-2(25)-3(27)+81$

$27-50-81+81$

$-23$

Therefore, the solution is $-23$
