Question

（729）sq - （271）sq solve this​

Answer 1

Hey friend,

Here is the solution :-

$({729})^{2} - ( {271})^{2} \\ \\ here \: a = 729 \: \: \: \: b = 271 \\ \\ {a}^{2} - {b}^{2} = (a + b)(a - b) \\ \\ (729)^{2} - (271)^{2} = (729 + 271)(729 - 271) \\ \\ = 729(729 + 271) - 271(729 + 271) \\ \\ = 531441 + 197559 - 197559 - 73441 \\ \\ = 458000 \\ \\ so \: (729)^{2} - (271)^{2} = 458000$

✨I hope this will help you....✨
