2√5((5+√3) + (5-√3)) =( 2√5 . (5+√3)) + (2√5 . (5-√3))
                               =(2.5 + √8) + (2.5 -√8)
                               =10.2√2 + 10-2√2
= 20√2 + 8√2
= 28√2
eh iya deh haha.. ulang deh nih :D sorry ya,,, human error biasa
hehe okeee
= ( 2.5 + √5.√3) + ( 2.5 - √5.√3)
=( 10 +√15 )+ (10 - √15)
= (10 + 3 √6 ) + ( 10 - 3 √6)
= 13√6 + 7√6
= 20√6 hehe :D
makasih banyak yaaa!!
sip deh buat kamu :) haha
