Answer 2

Hey friend,
Here is the answer you were looking for:
${(997)}^{2} \\ \\ = {(1000 - 3)}^{2} \\ \\ using \: identity \\ {(a - b)}^{2} = {(a)}^{2} + {(b)}^{2} - 2ab \\ \\ {(1000 - 3)}^{2} \\ \\ = {(1000)}^{2} + {(3)}^{2} - 2 \times 1000 \times 3 \\ \\ = 1000000 + 9 - 6000 \\ \\ = 1000009 - 6000 \\ \\ = 994009$

Hope this helps!!!
