Сократим дроби:
1) x^7/x^21 = x^7/(x^7 * x^14) = 1/x^14;
2) y^12/y^18 = y^(12 - 18) = y^(-6) = 1/y^6;
3) 8 * a^6/(6 * a^8) = 8/6 * a^(6 - 8) = 4/3 * 1/a^2;
4) 9 * a^6/(6 * a^8) = 3/2 * 1/a^2;
5) 10 * a^6 * b^6/(8 * a^8 * b^6) = 10/8 * a^6/a^8 * b^6/b^6 = 5/4 * 1/a^2;
6) 36 * x^12 * y^36/(96 * x^36 * y^96) = 6/16 * 1/x^24 * 1/y^60 = 3/8 * 1/x^24 * 1/y^60;
7) 12 * n^7 * p^9/(16 * n^7 * p^8) = 3/4 * p;
8) 64 * a^15 * b^27/(48 * a^27 * b^27) = 4/3 * 1/a^13.
