Answer 2

✪ 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.
