What is the proper way to ask?
How can we achieve this?
or
How we can archive this?
What's the difference between them?
If you want to form a question, how/what/which etc. should be followed by a verb. And here, the verb is 'can'.
So,
How can we achieve this?
forms a question.
Take another example.
How we do it
is not forming a question. You need an auxiliary verb there to form a question.
How do we do it?
I often teach my daughter in this way...
The first one is 'actually' a sentence and not a question.
[This is] how we can achieve this!
It's not possible to mark it as a sentence with an auxiliary verb in it placed after 'how'
[This is] how can we achieve this?
The latter requires question mark and the former does not!
Just a trick!
How we can do it
. What it means? Does it make sense?

instead of How can we
. That's why got this doubt. :-) Thanks for your answer.

The difference between these two sentences is too simple:
How can we achieve this? (This is a completed question.You are asking,what do I do? and then I achieve this)
How we can achieve this (This is not a completed question or sentence,only a phrase that describe how you do the action.)
example: If we study hard then we can pass the exam so "this is how we can achieve the success."(Think it like "This is our method to achieve the success")
