1. $\dfrac{a-b}{\sqrt[3]a-\sqrt[3]b}-\dfrac{a+b}{a^{\genfrac{}{}{}{}13}+b^{\genfrac{}{}{}{}13}}$;
2. $\dfrac{a+b}{a^{\genfrac{}{}{}{}23}-a^{\genfrac{}{}{}{}13}b^{\genfrac{}{}{}{}13}+b^{\genfrac{}{}{}{}23}}-\dfrac{a-b}{a^{\genfrac{}{}{}{}23}+a^{\genfrac{}{}{}{}13}b^{\genfrac{}{}{}{}13}+b^{\genfrac{}{}{}{}23}}$;
3. $\dfrac{a^{\genfrac{}{}{}{}23}+b^{\genfrac{}{}{}{}23}}{a-b}-\dfrac1{a^{\genfrac{}{}{}{}13}-b^{\genfrac{}{}{}{}13}}$;
4. $\dfrac{a^{\genfrac{}{}{}{}13}-b^{\genfrac{}{}{}{}13}}{a+b}-\dfrac1{a^{\genfrac{}{}{}{}23}-a^{\genfrac{}{}{}{}13}b^{\genfrac{}{}{}{}13}+b^{\genfrac{}{}{}{}23}}$.
