Пошаговое объяснение:
1)y'=24x^5-14x-9/x^2, y''=5*24x^4-14+18/x^3=120x^4-14+18/x^3
2) y'=5/x^2-7/2Vx+2cos2x-3e^3x, y''=-10/x^3+7/4Vx^3-4sin2x-9e^3x
3) y'=5*(7x^5-2x^3+8x)^4 * (35x^4-6x^2+8)
y''=u'v+uv', y''=20(7x^5-2x^3+8x)^3 * (35x^4-6x^2+8)*(35x^4-6x^2+8)+
+5(7x^5-2x^3+8x)^4 * (35x^4-6x^2+8)* (280x^3-12x)=5(7x^5-2x^3+8x)^3 *
(35x^4-6x^2+8)*(4(35x^4-6x^2+8)+280x^3-12x)
