根号6加1等于根号7吗? 根号7加根号6 分之一等于多少
\u6839\u53f77\u52a0\u6839\u53f76 \u5206\u4e4b1\u7b49\u4e8e\u591a\u5c11\u221a7 + \u221a(1/6)
= \u221a7 + \u221a6 / 6
1/(\u221a7+\u221a6)
=(\u221a7-\u221a6)/(7-6)
=(\u221a7-\u221a6)
不等于，谢谢，请采纳
不等于的，因为根号下6跟1不是同一个概念，请采纳
x=√7+√6
1/x=1/（√7+√6）
=(√7-√6)/(√7-√6)(√7+√6)
=(√7-√6)/(7-6)
=√7-√6
所以原式=(√7+√6+√7-√6)(√7+√6-√7+√6)
=2√7*2√6
=4√42
不等于
