c)(6√15-18x3+18√5)/6√3=√3(6√15+18√5-54)/18=6√3(√15+3√5-9)/18=
√3(√15+3√5-9)/3

d)8/5√5 + 2√5/2=8√5/25+√5=(8√5+25√5)/25=33√5/25

e)5/(2-√3)=5(2+√3)/(4-3)=5(2+√3)

f)(√2+1)/(√3+2√2)=(√2+1)(√3-2√2)/(3-8)=(√6-4+√3-2√2)/(-5)=
-(√6+√3-2√2-4)/5

g)(1+√3)/(1-√3)=(1+√3)²/(1-3)=(1+2√2+3)/(-2)=(4+2√2)/(-2)=2(2+√2)/(-2)=
-2-√2
