Answer 2

Step-by-step explanation:

Step 1: Put the value of m=1, n= -1 and p= 2

m^ 3 +n^ 3 +p ^3 −3mnp=(1)^ 3 +(−1) ^3 +(2)^ 3 −3*( 1)* (−1) *(2)

Step 2: Simplify to get the result

m^ 3+n^3 +p^ 3 −3mnp=1−1+8+6=14

Hence, the value of m 3 +n ^3 +p^ 3 −3mnp at m=1, n=-1 and p= 2 is 14.

Hope this helps...
