Final answer:
When x=3 and y=0, the value of x³ * y⁴ is 0 because any number multiplied by zero will result in zero.
Step-by-step explanation:
To find the value of x³ * y⁴ when x=3 and y=0, you simply substitute the values of x and y into the expression.
Replacing x with 3 and y with 0, we get:
3³ * 0⁴ = 27 * 0 = 0
Any number multiplied by zero is zero, hence, regardless of the value of x, as long as y is zero, the entire expression will equal zero.
