Just got done watching W1D4 of 1 month plan for quant, session 7. There were a few homework problems on roots but the video of session 6 never went over roots, just exponents. Some of the problems were about finding the diagonal of a square and hypotenuse of a triangle, etc., and the answer(s) were roots. Does gregmat go over roots and how to solve these problems are do they never show up again until the geometry section? also is there another video in any of the study plans that go over this?
