a) 3+√2 3+√2*√8 3+√16 3+4=7
-----------= ----------------=----------=-------------
√8 √8 *√8 √64 8
b)2-3√2
------------= 2-3√2*√50= 2-3*10= -28
√50 √50*√50 2500 50
c)1-2√6= 1-2√6*√54= 1-2*√324= 1-2*18= 1-36=-37
√54 √54*√54 54 54 = 54= 54
d)3+√6= 3+√6*√96= 3+√576= 3+24= 27
√96 = 96 = 96 = 96 = 96
e)√10-2= √10-2*√1000= -2*√10000= -200
√1000 = 1000 = 1000 = 1000
f)7+√3= 7+√3*√28= 7+√84=
√28 = 28 = 28
mam nadzieję że dobrze ;)
