here some typing mistake see below ,
( 7 +3√5)/(3+√5) -(7-3√5)/(3-√5)
={(7+3√5)(3 + √5)+(7-3√5)(3-√5)}/(9-5)
={ 21 +7√5 +9√5 +15 +21 -7√5-9√5 +15}/4
={42 +30)/4
=72/4 = 18
( 7 +3√5)/(3+√5) -(7-3√5)/(3-√5)
={(7+3√5)(3 + √5)+(7-3√5)(3-√5)}/(9-5)
={ 21 +7√5 +9√5 +15 +21 -7√5-9√5 +15}/4
={42 +30)/4
=72/4 = 18
