Answer:
The value of the expression for the given values of x,y and z is:
-23
Step-by-step explanation:
The algebraic expression is given by:
\(x^3-2y^2-3x^3+z^4\)
We are asked to evaluate the value of the expression when
\(x=3\ ,\ y=5\ and\ z=-3\)
Now, putting these values in the given expression we have:
\(=3^3-2(5)^2-3(3)^3+(-3)^4\\\\=3^3-2(5)^2-(3)^4+(3)^4\\\\=27-2\times 25+0\\\\=27-50\\\\=-23\)
Hence, the answer is: -23
