1 He will come and meet me next weekend.
2 should
3 3b/5a
4 4√70π
5 （√x+√y）(x+2√xy+y)/(x-y) 式子里的xy+y都在根号下
那步的步骤不会也可以问
1、come visit
2、show吧
3、0.1ab
4、根号70π
5、对不起，我也不会耶。。。
1.come see
2.第二题没错么？
3.根号下（5a分之（b的立方））
4.π是派么？？
是的话，280π
不是的话，280
5.你题目有问题
等于（根号X-根号Y）加上（（根号X-根号Y）减去（4根号XY））
1 作AF⊥BC于点F ，DG⊥BC于点G∵BD=DC，AD=4，BC=12 ∴BG=CG=6，FG=AD=4，BF=2 （1）若四边形ABED为等腰梯形则GE=BF=2 ∴CE=4
