Answer:
But what u wanted to do
how can we say this
Step-by-step explanation:
How do I know?" usually casts doubt on something that previously was assumed to be true. For example, if someone you've never heard of on the Internet asks you to send them US$1,200, after which they will send you information about a huge inheritance that you are owed, you might say:
How do I know that I'll ever hear from this person again after sending the money?
How do I know I can trust this person?
Or, about almost any answer on ELL:
How do I know that this person is describing English accurately?
It's also used in sophomoric philosophy:
How do I know that this is not all just a dream?
The point is to challenge an assumed proposition by asking for justification. One could answer by providing justification for the proposition in question.
How would I know?
"How would I know?" asks for a method of finding something out if a given proposition is true: something to check for. The word would indicates the conditional mood, suggesting that the question is about a hypothetical situation rather than a current one.
"How would I know if I've driven too far?" "If you come to a big, white barn, then you've definitely driven too far."
However, people also use the conditional mood as a polite "softener". "How do I know?" is quite challenging. It suggests that something has been carelessly or foolishly assumed. So, someone might ask "How would I know?" even about a present situation, in order to avoid sounding challenging.
Also, you might say "How would I know?" about a present situation if the matter in question is simply unknown:
How would I know if this car was stolen?
How would I know if I'm pregnant?
