(1)√10xy ÷\(\sqrt{x^{3}}\)
(2)√14mn\(\times\sqrt{\frac{7m}{n^{2}} \times}\sqrt{\frac{1}{6n}}\)
(1)√10xy ÷\(\sqrt{x^{3}}\)
(2)√14mn\(\times\sqrt{\frac{7m}{n^{2}} \times}\sqrt{\frac{1}{6n}}\)
答案 / 解析
答案(f_answer)
(1) (2)
解析(f_ways)
x 3n (1)由√10xy,\(\sqrt{\frac{x^{3}}{6y^{2}}}\)有意义,得到x> 0,y> 0,√10xy÷\(\sqrt{\frac{x^{3}}{6y^{2}}}=√10xy\times \frac{6y^{2}}{x^{3}} =\sqrt{\frac{60xy^{3}}{x^{3}}}=√ \frac{60y^{3}}{x^{2}} = \frac{y}{x}\)√60y=\(\frac{y}{x} \times 2√15y= 2y√15y\); x (2)由√14mn,\(\sqrt{\frac{7m}{n^{2}},√ \frac{1}{6n}}\)有意义,得到 m≥0,n> 0,√14mn\(\times\sqrt{\frac{7m}{n^{2}} \times}\sqrt{\frac{1}{6n}}=\)√14mn\(\times \frac{7m}{n^{2}} \times \frac{1}{6n} =√ \frac{98m^{2}n}{6n^{3}} =√ \frac{49m^{2}}{3n^{2}} = =\). 7m 7m√3 n√3 3n
