If m^(-1) = -1/4 then m^(-2) is equal to  Pick one
A) -9  B) -3  C) -1/9  D) 1/16  E) 9
You made a mistake here.   You're right till   m^-2 = 1/m^2 and m^-1 = 1/m^1 = 1/m   given m^-1 1/  1=

1/m   given m^-1= -(1/4) so, 1/m = -(1/4) solving this, m = -4   Now, m^-2 = 1/m^2 = 1/(-4)^2 = 1/16 ANS 1/16
