Вычислить производные: у=3√х+4/4√х3-3/4√х: у=√х-1/3√х4: у = (х3-5 х+7) (√х-4*4√х-2/√3 х

1) (y) ' = ((3√x + 4) ' * (4√x3 - 3/4√x) - (3√x + 4) * (4√x3 - 3/4√x) ') / (4√x3 - 3/4√x) ^2 = ((3 / 2√x) * (4√x3 - 3/4√x) - (3√x + 4) * (4/3 * x^ (-2/3) - 3/8√x) / (4√x3 - 3/4√x) ^2.

2) (y) ' = (√x) ' - (1/3√x^4) ' = 1/2√x - 2/3x.

3) = (x^3 - 5x + 7) ' * (√ (x - 4) * 4√ (x - 2) / √3x) + (x^3 - 5x + 7) * (√ (x - 4) * 4√ (x - 2) / √3x) ' = (3x^2 - 5) * (√ (x - 4) * 4√ (x - 2) / √3x) + (x^3 - 5x + 7) * (((√ (x - 4) ' * 4√ (x - 2) + (4√ (x - 2)) ' * (√ (x - 4) * √3x - √ (x - 4) * 4√ (x - 2) * (√3x) ' / (√3x) ^2.
