Evaluate each of the following to three significant figures and express each answer in SI units using an appropriate prefix:(200kN)^2?

I can't agree with the answer from hcbiochem.
He has answered the question of
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
