Answer :
You need to plug in the values of m and n to work this problem. The problem would look like the foolwing:
2(-2 + 1) - 3^3
2(-1) - 3 * 3 * 3
-2 - 27
-29
2(-2 + 1) - 3^3
2(-1) - 3 * 3 * 3
-2 - 27
-29
[tex]Put\ values\ of\ m=-2;\ n=3\ in\ expression\ 2(m+1)-n^3:\\\\2(-2+1)-3^3\\\\Use\ PEMDAS:\\\\2(-1)-27=-2-27=-29[/tex]
