Избавьтесь от иррациональности в знаменателе дроби:
1) [tex] \frac{y}{ \sqrt{x+ \sqrt{ x^{2} - y^{2} } } } [/tex]

2) [tex] \frac{ \sqrt{3 \sqrt{2}-2 \sqrt{3} } }{ \sqrt{2 \sqrt{3}+3 \sqrt{2} } } [/tex]

3) [tex] \frac{4}{ \sqrt{2}+ \sqrt{6+4 \sqrt{2} } } [/tex]

4) [tex] \frac{50}{3+ \sqrt{2}- \sqrt{1+ \sqrt{2} } } [/tex]

Упростите выражение:
1) [tex] \sqrt{12+ \sqrt{63}- \sqrt{10,5} } [/tex]

2) [tex] \sqrt{|12 \sqrt{3}-21| } - \sqrt{12 \sqrt{3}+21 } [/tex]

3) [tex] \sqrt{a+- \sqrt{ a^{2}-b^{2} } } [/tex]
