Answer 1

$\frac{3- \sqrt{3} }{2 \sqrt{3} }= \frac{ \sqrt{3}( \sqrt{3}-1) }{2 \sqrt{3} } = \frac{ \sqrt{3}-1 }{2}$

$\frac{4b-2}{2 \sqrt{b}- \sqrt{2} }= \frac{(2 \sqrt{b}- \sqrt{2})(2 \sqrt{b}+ \sqrt{2}) }{2 \sqrt{b}- \sqrt{2} } =2 \sqrt{b} + \sqrt{2}$

(3-√3)/2√3=(√3(√3-1)) /2√3=(√3-1)/2

(4b-2)/(2√b-√2)=((2√b-√2)(2√b+√2)) / (2√b-√2)=2√b+√2
