I don't know how we should solve the problem.这how后面的是宾语从句

I don't know how we should solve the problem.这how后面的是宾语从句 We really don't know how we should solve the problem 改为同义句 W I don't know how to solve the problem.的同义句 i don't know how to solve this problem. I don't know how to solve the problem.Can you _______a good I don't know how to solve the problem .Can you ____a good id I still don't know how to solve this maths problem.Can you g 这个是那种从句?i don't know how to deal with some problem. I don’t know how to do it .中,how to do it是否为宾语从句,如果是,那宾语从句的主 I don't know, how much did the book cost.改为宾语从句,谢了 I don't know how they deal with the problem=I don't know （ ） 请问i don't know (how i should do) next 这句话为啥是错的?
