Answer 1

(√97+2)²= 97+4√97+4= 101+4√97

(√32-3)²= 32-6√32+9= 41-6√32

1/(3-√7)= (3+√7)/(9-7)= (3+√7)/2

1/(6-√21)= (6+√21)/(36-21)= (6+√21)/15

(√20-√5)√5= √100-√25= 10-5=5

(√18-√2)√2= √36-√4= 6-2=4

√54/6= √9=3

√28/7= √4=2

√5*18*10= √900= 30

√7*12*21= √1764=42

√21*14/6= √49= 7

√35*21/15= √49= 7

(2-√3+2+√3)/(4-3)= 4

(7-√47+7+√47)/(49-47)= 14/2= 7

(√37+6-√37+6)/(37-36)= 12
