Real numbers, yes Find the following values 【1】 - √ 49 / 164 [2] & # 179; √ - 1 [3] √ 0.16 [4] & # 179; √ 125 / 27 Compare the number of each group 【1】 | - 1.5 |, 1.5 [2] 1.414, √ 2 [3] two thirds, 0.667 Given that x < 2pai [3.14], X is an integer, find X
【1】 - √ 49 out of 164 = - √ 41 / 7 [2] & # - 179; √ - 1 = - 1 [3] √ 0.16 = 0.4 [4] & # - 179; √ 125 out of 27 = 3 / 5 compare the number of each group [1] | - 1.5 |, 1.5 [2] 1.414, √ 2 [3] two thirds, 0.66667 [1] | - 1.5 | = 1.5 [2] 1.414 0.6666
