3m^-3+3m^-3=18 so what does M equal?

Solve for m:
6/m^3 = 18

Take the reciprocal of both sides:
m^3/6 = 1/18

Multiply both sides by 6:
m^3 = 1/3

Taking cube roots gives 1/3^(1/3) times the third roots of unity:
Answer: |m = -(-1/3)^(1/3)          or m = 1/3^(1/3)          or m = (-1)^(2/3)/3^(1/3)
