    I can't agree with the answer from hcbiochem.

    He has answered the question of 

    (200^2)kN,

    but that is not (200 kN)^2.

    Instead, (200 kN)^2 is

    40000 * 1000000 kg^2 m^2/s^4,

    or 40000 Mg^2 m^2/s^4.

    I acknowledge that the teacher who asked the question may have MEANT to ask about (200^2) kN...but that didn't happen!

    200 kN)^2 = 40000 kN X (1 MN/1000 kN) = 40.0 MN
