the student needed to place a ten outside the radical, as a perfect square of 100 composes 200. This way, a two should be left under the radical sign. Also, this would be about 14.1 because 14^2 is 196 and 15^2 is 225. The correct answer must be less than 225, more than 196, but closer to 196. Therefore, a .1 is added to the 14

(a.) Her reasoning is incorrect because the closest perfect square is not 200, it is 49.

(b)

We can estimate the square root of 200 with 196 because it is the closest perfect square. square root of 296 is 14.
