Answer:
240
Explanation:
To evaluate the expression for specific numerical values, put the numbers in place of the corresponding variables, and do the arithmetic. A calculator or spreadsheet can help you with this.
p^2q^2+pq–q^3–p^3
= 4²(-4)² +4(-4) -(-4)³ -4³
= 4⁴ -4² +4³ -4³
= 4²(4² -1) = 16(15) = 240
The value of the expression is 240.
