hey!!!
(598)² = (600-2)²
we will use second identity :- (a-b)² = a² - 2ab + b²
here, a = 600 and b = 2
= (600)² - 2 ( 600 × 2 ) + (2)²
= 360000 - 2 ( 1200 ) + 4
= 360000 - 2400 + 4
= 357604
cheers!!!

Question :
Evaluate: (598)².
Please solve it.
Solution :
(598)² = (600-2)²
Identity to be used :
(a-b)² = a²+b²-2ab
(600-2)² = 600²+2²-2(600)(2)
= 360000+4-2400
= 360004-2400
= 357,604
