Answer 2

Given:

987 = 66

765=83

543=81

To find:

321=?

Solution:

$\Rightarrow 9^2+7^2-8^2 = 66 \\\to 81+49-64\\\to 66 \ \ reverse \ 66 \\\\\Rightarrow 7^2+5^2-6^2=83\\\to 49+25-36\\\to 38\ \ reverse \ 83\\\\\Rightarrow 543=81\\\to 5^2+3^2-4^2 \\\to 25+9-16\\\to 18 \ \ \ reverse \ 81$

Similarly:

$\Rightarrow 3^2+1^2 -2^2=?\\\to 9+1-4\\\to 6$

The final answer is "6" because it is a single digit.
