The answer is 3.

Step-by-step Step-by-step explanation:

Solution :

Finding the value of a square minus b square.

`{\implies{\sf{a \: square \: minus \: b \: square}}}`

`{\implies{\sf{{a}^(2) - {b}^(2)}}}`

`{\implies{\sf{{2}^(2) - {1}^(2)}}}`

`{\implies{\sf{{2 * 2} - {1 * 1}}}}`

`{\implies{\sf{4 - 1}}}`

`{\implies{\sf{\underline{\underline{3}}}}}`

Hence, the answer is 3.
