1. sqrt(2/3) / sqrt(5) = sqrt(2/15) around 0.3651483716701107
2. sqrt(6) / sqrt(24) = sqrt(6) / sqrt(6 * (2 * 2)) = sqrt(6) / (sqrt(6) * 2) = 1 / 2 = 0.5
3. -sqrt(4) /sqrt(1/2) = -sqrt(4 / 0.5) = - sqrt(8) around -2.82842712474619
4. sqrt (2/15) / sqrt(3/8) = sqrt((2/15) / (3/8)) = sqrt((2/15) * (8/3)) = sqrt(16/45) = 4/sqrt(45) = 4/(3 * sqrt(5)) around 0.5962847939999439
5. sqrt(182) = sqrt(2 * 91) = sqrt(2 * 7 * 13) = sqrt(2) * sqrt(7) * sqrt(13) around 13.49073756323204
6. what is 二平方 三平方
