Упростите выражение \(\frac{a^{\frac{2}{3}}+b^{\frac{2}{3}}}{a-b}-\frac{1}{a^{\frac{1}{3}}-b^{\frac{1}{3}}}.\)
- \(-\frac{a^{\frac{1}{3}}b^{\frac{1}{3}}}{a-b}\)
- \(\frac{a^{\frac{1}{3}}b^{\frac{1}{3}}}{a-b}\)
- \(-\frac{a^{\frac{1}{3}}b^{\frac{1}{3}}}{a^{\frac{1}{3}}-b^{\frac{1}{3}}}\)
- \(\frac{a^{\frac{1}{3}}b^{\frac{1}{3}}}{a^{\frac{1}{3}}-b^{\frac{1}{3}}}\)
