Answer:
(1/3)^-2+(1/4)^-2+(1/5)^-2-(1/6)^-2.
(1/3)^-2=1/0.111111111111=9.
(1/4)^-2=1/0.0625=16.
(1/5)^-2=1/0.04=25.
(1/6)^-2=1/0.027777777777=36.
(1/3)^-2+(1/4)^-2+(1/5)^-2-(1/6)^-2=9+16+25-36. (Because (1/3)^-2=9, (1/4)^-2=16, (1/5)^-2=25 & (1/6)^-2=36).
(1/3)^-2+(1/4)^-2+(1/5)^-2-(1/6)^-2=25+25-36.
(1/3)^-2+(1/4)^-2+(1/5)^-2-(1/6)^-2=50-36.
(1/3)^-2+(1/4)^-2+(1/5)^-2-(1/6)^-2=14.
I think this is your answer.
