Hello guys, i have watched tutorials, YouTube, google, and here on this thread and i still didn't understand how miners in the end get the so called "Blockhash".

Hi. This question is about bitcoin block structure, not about mining.

This means that
* if you're a technical guy you should move the topic to Development & Technical Discussion; then you'll get good technically accurate answers. (this would be the best option imho, this looks like a technical question to me)
* if you're a not so technical newbie, this may better go to Beginners & Help.

Now, about your question, you may not have been looking for the right websites. And sources of information.
One direct explanation come from https://learnmeabitcoin.com/ which is one very good source for learning:

You get a Block Hash by hashing the block header through SHA256 twice.

If you go to the source of this quote, you'll get more details.

Hello guys, i have watched tutorials, YouTube, google, and here on this thread and i still didn't understand how miners in the end get the so called "Blockhash".

can someone please explain to me with the following example if it's possible?

Let's take block number: #755118 it's blockhash is: 00000000000000000004263b29bf5bf2dc8de62ba926a14b77f123fece4d3d5e it's Merkle root: fe26443a7f9736eb317d6fff513f877d74c8dfb4107045915b820bd31274faed
and finally it's nonce: 91615120

        And block number: #755119 it's blockhash is: 000000000000000000024f691092adc85ce52ab7e4dc4934e1c78d098afa2dfb it's Merkle root: 66e1402552f44695444aa3a201e7330a479f14dafa8f4b9a0496a53c6e950daa and finally it's nonce: 2254353472

what process had been done to get blockhash #755119?

Thank you
