‼️‼️‼️‼️‼️‼️‼️‼️‼️‼️‼️‼️‼️‼️‼️‼️‼️‼ ️‼️‼️‼️‼️ ! explain and only answer if you know you have the correct ! evaluate the following expression using the values given: x^3 - 2y^2 - 3x^3 + z^4 x=3 y=5 z = -3

We are given the expression x³ - 2y² - 3x³ + z⁴. We have to evaluate it at a given set of x, y, and z values. Before then, let's combine like terms.

x³ - 2y² - 3x³ + z⁴

= -2x³ - 2y² + z⁴ <-- by combining like terms

Now we evaluate for x=3 y=5 z = -3

= -2(3³) - 2(5²) + (-3⁴) <-- by putting in for x, y, z

= -2(27) - 2(25) + 81 <--- parentheses and exponents first in order of operations

= -54 - 50 + 81 < multiplication is next

= -4 + 81

= 77

Thus, we evaluate and it's 77.
