Answer

6x26x^2

Step-by-step solution

2 steps

Here's the derivation for question 6.b:

  1. Simplify the expression for YY.

    Y=X2(2x)Y = X^2 (2x) Y=2x2+1Y = 2x^{2+1} Y=2x3Y = 2x^3
  2. Differentiate the simplified expression with respect to xx.

    Recall that ddx(axn)=naxn−1\frac{d}{dx}(ax^n) = nax^{n-1}.

    dYdx=ddx(2x3)\frac{dY}{dx} = \frac{d}{dx}(2x^3) dYdx=2(3)x3−1\frac{dY}{dx} = 2(3)x^{3-1} dYdx=6x2\frac{dY}{dx} = 6x^2

    The derivative is:

    6x26x^2
