1) y=9x^1/9+5x^1/5+3 2) y=9x^1/9+6x^1/6+10x^4/5+6x^1/3+4x+2

Вычислим производные функций:

1) y = 9 * x^ (1/9) + 5 * x^ (1/5) + 3;

y ' = (9 * x^ (1/9) + 5 * x^ (1/5) + 3) ' = 9 * 1/9 * x^ (1/9 - 1) + 5 * 1/5 * x^ (1/5 - 1) + 0 = x^ (1/9 - 9/9) + x^ (1/5 - 5/5) = x^ (-8/9) + x^ (-4/5).

2) y = 9 * x^1/9 + 6 * x^1/6 + 10 * x^4/5 + 6 * x^1/3 + 4 * x + 2;

y ' = (9 * x^1/9 + 6 * x^1/6 + 10 * x^4/5 + 6 * x^1/3 + 4 * x + 2) ' = 9 * 1/9 * x^ (1/9 - 1) + 6 * 1/6 * x^ (1/6 - 1) + 10 * 4/5 * x^ (4/5 - 1) + 6 * 1/3 * x^ (1/3 - 1) + 4 * 1 + 0 = x^ (-8/9) + x6 (-5/6) + 8 * x^ (-1/5) + 2 * x^ (-2/3) + 4.
