Are you saying that the question was too easy, or it was too hard?
Normally your complaints are about mental arithmetic questions that are too easy.
So I'm not sure.
Personally I thought it was harder then the usual arithmetic questions they have, but certainly not impossible, if you give it a bit of thought. it's just 400 x 100, so the square root is 20 x 10 = 200.
You could even do it as 4 x 10,000, if you know that the square root of 10,000 is 100, then it's just twice that.
The square root of 400,000 would be a lot harder, though, because the above tricks won't work. You're left with 40 x 10,000, so it's a hundred times root 40, which is about 6.3, approximating, because it's about a third of the way between six squared (36) and seven squared (49). So it's approximately 630. The actual answer is 632.4, to one decimal place.
I think that would be a bit hard for a Chase question.
