Q. Find the derivative of the following function.\newliney=log2(9x3) y=\log _{2}\left(-9 x^{3}\right) \newlineAnswer: y= y^{\prime}=
  1. Identify Function: Identify the function and its components.\newlineWe are given y=log2(9x3)y = \log_2(-9x^3), which is a logarithmic function with base 22. We need to find the derivative of this function with respect to xx.
  2. Apply Rule: Apply the logarithmic differentiation rule.\newlineThe derivative of logb(u)\log_b(u) with respect to xx is (1/u)(du/dx)(1/log(b))(1/u) \cdot (du/dx) \cdot (1/\log(b)), where uu is a function of xx and bb is the base of the logarithm. In our case, u=9x3u = -9x^3 and b=2b = 2.
  3. Differentiate Inner Function: Differentiate the inner function u=9x3u = -9x^3 with respect to xx. The derivative of uu with respect to xx is dudx=ddx(9x3)=27x2\frac{du}{dx} = \frac{d}{dx}(-9x^3) = -27x^2.
  4. Substitute Derivative: Substitute the derivative of uu into the differentiation formula.\newlineUsing the result from Step 33, we substitute dudx\frac{du}{dx} into the formula from Step 22 to get y=(1(9x3))(27x2)(1log(2)).y' = \left(\frac{1}{(-9x^3)}\right) * (-27x^2) * \left(\frac{1}{\log(2)}\right).
  5. Simplify Expression: Simplify the expression.\newlineWe can simplify the expression by multiplying the terms together. This gives us y=27x29x3×1log(2)=3x×1log(2)y' = \frac{-27x^2}{-9x^3} \times \frac{1}{\log(2)} = \frac{3}{x} \times \frac{1}{\log(2)}.
  6. Check for Errors: Check for any mathematical errors.\newlineThere are no mathematical errors in the previous steps. The derivative has been correctly calculated.
