✪ Question ✪
Find the value of (499)² using identity.
✪ To find ✪
The value.
✪ Identity ✪
(a-b)² = a²-2ab+b²
✪ Solution ✪
We have to find (499)².
We can take 499 as (500-1).
So, according to the identity, here a = 500 and b = 1.
∴ (499)²
= (500-1)²
= (500)²-(2×500×1)+1²
= 250000-1000+1
= 249000+1
= 249001
✪ Hence ✪
(499)² = 249001
✪ Therefore ✪
The value of (499)² is 249001.
