Answer 2

(√5+3)²=(√5)²+2*√5*3+3²=5+6√5+9=14+6√5
(4+√6)²=4²+2*√6*4+(√6)²=16+8√6+6=22+√6
(√2+√7)²=(√2)²+2*√2*√7+(√7)²=2+2√14+7=9+2√14
(√8+√5)²=(√8)²+2*√8*√5+(√5)³=8+2√45+5=13+6√5
(2√3+3)²=(2√3)²+2*2√3*3+3²=12+12√3+9=31+12√3
(√5+2√10)²=(√5)²+2*√5*2√10+(2√10)²=5+4√50+40=45+4√50
(3√2+2√3)²=(3√2)²+2*3√2*2√3+(2√3)²=18+12√6+12=30+12√6
(3√5+2√15)²=(3√5)²+2*3√5*2√15+(2√15)²=45+12√75+60=105+12√75
(√12+2√27)²=(2√3)²+2*2√3*3√3+(3√3)²=12+12√9+27=39+36=75
√9⇒3⇒12*3⇒36
