Q. Find the derivative of the following function.\newliney=log3(8x3+x2) y=\log _{3}\left(8 x^{3}+x^{2}\right) \newlineAnswer: y= y^{\prime}=
  1. Identify Function & Derivative: Identify the function and the type of derivative needed.\newlineWe need to find the derivative of the function yy with respect to xx, where y=log3(8x3+x2)y = \log_3(8x^3 + x^2). This is a logarithmic differentiation problem with a base other than ee.
  2. Apply Logarithmic Differentiation 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=8x3+x2u = 8x^3 + x^2 and b=3b = 3.
  3. Differentiate Inside Function: Differentiate the inside function u=8x3+x2u = 8x^3 + x^2 with respect to xx. Using the power rule, the derivative of uu with respect to xx is dudx=24x2+2x\frac{du}{dx} = 24x^2 + 2x.
  4. Substitute Derivative into Formula: Substitute the derivative of uu into the formula from Step 22.\newlineWe have dudx=24x2+2x\frac{du}{dx} = 24x^2 + 2x and u=8x3+x2u = 8x^3 + x^2. Substituting these into the formula gives us y=18x3+x2(24x2+2x)1log(3)y' = \frac{1}{8x^3 + x^2} \cdot (24x^2 + 2x) \cdot \frac{1}{\log(3)}.
  5. Simplify Expression: Simplify the expression.\newlineWe can simplify the expression by multiplying the terms together. This gives us y=24x2+2x(8x3+x2)log(3)y' = \frac{24x^2 + 2x}{(8x^3 + x^2) \cdot \log(3)}.
  6. Check for Simplifications: Check for any possible simplifications. In this case, there is no further simplification that can be done without changing the expression significantly. So, we leave the derivative in its current form.
