GIVEN
a and b are rational numbers...
To find ; (√ a+√b)(√a-√b) is __
According to the identity
(a+b) (a-b) = a²- b²
so ,
(√ a+√b)(√a-√b) = (√a)² - (√b)²
= a - b ...
It is already stated that a and b are rational numbers..
Thus,WHEN A RATIONAL NUMBER IS SUBTRACTED FROM OTHER RATIONAL NUMBER ,IT IS ALWAYS RATIONAL NUMBER
ØPTION C IS CORRECT!!
