Answer 1

1. Efectuati dupa ce ati scos factorii de sub radical:
a)√243-√363-√507+√432 =9√3-11√3-13√3+12√3 =-3√3 
b) √216 - √726 - 7√6 + √486= 36√6 - 11√6 - 7√6 + 9√6=27√6 
c)√3125 - √3087 - √720 + √2023=25√5 - 21√7 - 12√5 + 17√7=13√5 - 4√7
d)√675 - √1620 - √845 + √588=15√3 -18√5 - 13√5 + 14√3=28√3-31√5
