Discussion Board
Explanation

a² - b² = (a+b)(a-b)
So as per the above formula,
We get, a = 2.3
b = .75
{(2.3)2 – (.75)2}/3 = (3.05 × 1.55)/3
= 1.573333 ˜ 1.6

not getting to solve it in easy way

if we take
2.3-> 2
.75-> 1
4-1=3
3/3=1
this is true that it consists of one then how to find the similar digit after the point.
