under root me number h to usi se multiply aur divide krte h
e.g.√2×√2/√2=2/√2
second type
yadi number is type ka h
5/(2-√5)×(2+√5/2+√5)
=5(2+√5)/(2)²-(√5)²
5(2+√5)/4-5
-5(2+√5)
third type
yadi number numerator divide by denominator type ka h to
denominator ka sign change karo aur usi se multiply aur divide kar do
e.g.(x+y)/(x-y)×(x+y)/(x+y)
(x+y)²/x²-y²
e.g.√2×√2/√2=2/√2
second type
yadi number is type ka h
5/(2-√5)×(2+√5/2+√5)
