How to find values of Prev_Hash and Tx_Root https://bitcoin.stackexchange.com/a/13347/27951

Based upon the answer here, it seems there's values per block with each Prev_Hash and also Tx_Root

There doesn't seem to be much documentation for how to access these. How can I find the Prev_Hash and the Tx_Root of the most recent block for example?

Thanks
Look at a block on a block explorer. 



Here the Prev_Hash is called 'Previous Block' and the Tx_Root is called 'Merkle Root'.

For more technical info, take a look at the Protocol Documentation.
