Answer 1

$sqrt{60} +(sqrt{5}-sqrt{3})^2=2sqrt{15}+5-2sqrt{15}+3=8\(sqrt{3+2sqrt{2}}-sqrt{3-2sqrt{2}})^2=3+2sqrt{2}-2sqrt{9-8}+3-2sqrt{2}=4$

Answer 2

d) (√3+2√2-√3-2√2)²=(√(1+√2)²-√3-2√2)²=(√(1+√2)²-(√(1-√2)²)²=(1+√2-√(1-√2)²)²=(1+√2-(√2-1))²=(1+√2-√2+1)²=(1+1)²=2²=4

b)√60+(√5-√3)²=2√15+(√5-√3)²=2√15+5-2√15+3=5+3=8
