Here are the derivatives for each function:

1) Given y=2x+x23−1xy = \frac{2}{\sqrt{x}} + \sqrt[3]{x^2} - \frac{1}{x}

  1. Rewrite the terms using exponents.

    y=2x−1/2+x2/3−x−1y = 2x^{-1/2} + x^{2/3} - x^{-1}
  2. Differentiate each term using the power rule ddx(axn)=anxn−1\frac{d}{dx}(ax^n) = anx^{n-1}.

    dydx=2(−12)x−1/2−1+23x2/3−1−(−1)x−1−1\frac{dy}{dx} = 2 \left(-\frac{1}{2}\right)x^{-1/2 - 1} + \frac{2}{3}x^{2/3 - 1} - (-1)x^{-1 - 1} dydx=−x−3/2+23x−1/3+x−2\frac{dy}{dx} = -x^{-3/2} + \frac{2}{3}x^{-1/3} + x^{-2}
  3. Rewrite with positive exponents and radicals.

    dydx=−1x3/2+23x1/3+1x2\frac{dy}{dx} = -\frac{1}{x^{3/2}} + \frac{2}{3x^{1/3}} + \frac{1}{x^2} dydx=−1xx+23x3+1x2\frac{dy}{dx} = -\frac{1}{x\sqrt{x}} + \frac{2}{3\sqrt[3]{x}} + \frac{1}{x^2}

    The final answer is dydx=−1xx+23x3+1x2\boxed{\frac{dy}{dx} = -\frac{1}{x\sqrt{x}} + \frac{2}{3\sqrt[3]{x}} + \frac{1}{x^2}}.

    2) Given y=3x4+(2xp)0−3q+16x34y = 3x^4 + (2xp)^0 - 3q + \frac{16}{\sqrt[4]{x^3}}

  4. Simplify the terms.

    Remember that any non-zero number raised to the power of 0 is 1, and qq is a constant.

    y=3x4+1−3q+16x−3/4y = 3x^4 + 1 - 3q + 16x^{-3/4}
  5. Differentiate each term.

    The derivative of a constant is 0.

    dydx=ddx(3x4)+ddx(1)−ddx(3q)+ddx(16x−3/4)\frac{dy}{dx} = \frac{d}{dx}(3x^4) + \frac{d}{dx}(1) - \frac{d}{dx}(3q) + \frac{d}{dx}(16x^{-3/4}) dydx=3(4)x4−1+0−0+16(−34)x−3/4−1\frac{dy}{dx} = 3(4)x^{4-1} + 0 - 0 + 16\left(-\frac{3}{4}\right)x^{-3/4 - 1} dydx=12x3−12x−7/4\frac{dy}{dx} = 12x^3 - 12x^{-7/4}
  6. Rewrite with positive exponents and radicals.

    dydx=12x3−12x7/4\frac{dy}{dx} = 12x^3 - \frac{12}{x^{7/4}} dydx=12x3−12xx34\frac{dy}{dx} = 12x^3 - \frac{12}{x\sqrt[4]{x^3}}

    The final answer is dydx=12x3−12xx34\boxed{\frac{dy}{dx} = 12x^3 - \frac{12}{x\sqrt[4]{x^3}}}.

    3) Given y=4x2+3x+2x3y = \frac{4x^2 + 3x + 2}{x^3}

  7. Split the fraction into individual terms and simplify using exponent rules.

    y=4x2x3+3xx3+2x3y = \frac{4x^2}{x^3} + \frac{3x}{x^3} + \frac{2}{x^3} y=4x−1+3x−2+2x−3y = 4x^{-1} + 3x^{-2} + 2x^{-3}
  8. Differentiate each term using the power rule.

    dydx=4(−1)x−1−1+3(−2)x−2−1+2(−3)x−3−1\frac{dy}{dx} = 4(-1)x^{-1-1} + 3(-2)x^{-2-1} + 2(-3)x^{-3-1} dydx=−4x−2−6x−3−6x−4\frac{dy}{dx} = -4x^{-2} - 6x^{-3} - 6x^{-4}
  9. Rewrite with positive exponents.

    dydx=−4x2−6x3−6x4\frac{dy}{dx} = -\frac{4}{x^2} - \frac{6}{x^3} - \frac{6}{x^4}

    The final answer is dydx=−4x2−6x3−6x4\boxed{\frac{dy}{dx} = -\frac{4}{x^2} - \frac{6}{x^3} - \frac{6}{x^4}}.

    4) Given y=(−2x2)3y = (-2x^2)^3

  10. Simplify the expression for yy.

    y=(−2)3(x2)3y = (-2)^3 (x^2)^3 y=−8x2⋅3y = -8x^{2 \cdot 3} y=−8x6y = -8x^6
  11. Differentiate using the power rule.

    dydx=−8(6)x6−1\frac{dy}{dx} = -8(6)x^{6-1} dydx=−48x5\frac{dy}{dx} = -48x^5

    The final answer is dydx=−48x5\boxed{\frac{dy}{dx} = -48x^5}.

    5) Given y=(2x2−3)(3x−2)y = (2x^2 - 3)(3x - 2)

  12. Expand the expression for yy by multiplying the two binomials.

    y=(2x2)(3x)+(2x2)(−2)+(−3)(3x)+(−3)(−2)y = (2x^2)(3x) + (2x^2)(-2) + (-3)(3x) + (-3)(-2) y=6x3−4x2−9x+6y = 6x^3 - 4x^2 - 9x + 6
  13. Differentiate each term using the power rule.

    dydx=ddx(6x3)−ddx(4x2)−ddx(9x)+ddx(6)\frac{dy}{dx} = \frac{d}{dx}(6x^3) - \frac{d}{dx}(4x^2) - \frac{d}{dx}(9x) + \frac{d}{dx}(6) dydx=6(3)x3−1−4(2)x2−1−9(1)x1−1+0\frac{dy}{dx} = 6(3)x^{3-1} - 4(2)x^{2-1} - 9(1)x^{1-1} + 0 dydx=18x2−8x−9x0\frac{dy}{dx} = 18x^2 - 8x - 9x^0 dydx=18x2−8x−9\frac{dy}{dx} = 18x^2 - 8x - 9

    The final answer is dydx=18x2−8x−9\boxed{\frac{dy}{dx} = 18x^2 - 8x - 9}.
