It's pretty simple,

Use the formula (a-b)²,

Write 999999999999 as 1000000000000,

Now let this be a, And b be 1,

(a-b)² = a²+b² - 2ab,

=> a² = 10^24 + 1 - 2*10^12,

=> (999999999999)² = The answer is in the photo !

Please do refer it !

Thank you ! Hope you understand, Have a great day,

By the way I used python code to execute it in scientific notation, And it is not a plagiarism,

Hope you understand, Have a great day !
