Answer: The value of the given expression = 101
Step-by-step explanation:
Given: p=4,q=-3,and r=2
To find the value of expression [tex]p^3+q^3-r^3-3pqr[/tex].
Substitute all values p=4,q=-3,and r=2 in the expression, we get
[tex]4^3+(-3)^3-(2)^3-3(4)(-3)(2)\\\\=64-27-8+72\\\\=101[/tex]
Hence, the value of the given expression = 101
