Answer 1

3-√3
--------------- = -0,4471
√15-3*√5

3-√3=1,2679
3*√5=6,7082
√15=3,8729
3,8729-6,7082=-2,8353
1,2679:(-2,8353)=-0,4471

3*√3+2*√2
------------------=2,55
√3+√2

√3=1,732
√2=1,414

Answer 2

35
√7*(√3-1)/7(√3-2)=(√3-1)/√7(√3-2)=(√3-1)/(√21-2√7)
36
√3(√3-1)/√15(1-√3)=-1/√5
37
(√3+√2)(3-√6+2)/(√3+√2)=5-√6
