Answer 2

The square root of 64 is 8, therefore, the square root of 6400 is 80. 90 squared is 8100. So somewhere around 84 squared should produce a number fairly near to 7000 and hopefully slightly above it. 84 squared is, in fact, 7056. This is the closest square number above 7000.

7056–7000 is 56.
