Full solution

Q. Let g(x)=x43 g(x)=x^{\frac{4}{3}} .\newlineg(27)= g^{\prime}(27)=
  1. Apply Power Rule: We need to find the derivative of the function g(x)=x43g(x) = x^{\frac{4}{3}}. To do this, we will use the power rule for differentiation, which states that if g(x)=xng(x) = x^n, then g(x)=nxn1g'(x) = n \cdot x^{n-1}.
  2. Calculate Exponent: Applying the power rule to g(x)=x43g(x) = x^{\frac{4}{3}}, we get g(x)=43x(431)g'(x) = \frac{4}{3}\cdot x^{(\frac{4}{3}-1)}. We need to subtract 11 from the exponent 43\frac{4}{3} to apply the power rule correctly.
  3. Evaluate Derivative at x=27x=27: Simplifying the exponent, we have (43)1=(43)(33)=(13)(\frac{4}{3}) - 1 = (\frac{4}{3}) - (\frac{3}{3}) = (\frac{1}{3}). So, g(x)=(43)x(13)g'(x) = (\frac{4}{3})\cdot x^{(\frac{1}{3})}.
  4. Find Cube Root: Now we need to evaluate the derivative at x=27x = 27. So, we substitute xx with 2727 in the derivative to get g(27)=(43)(27)13g'(27) = (\frac{4}{3})\cdot(27)^{\frac{1}{3}}.
  5. Substitute and Simplify: To simplify (27)1/3(27)^{1/3}, we need to find the cube root of 2727. The cube root of 2727 is 33 because 33=273^3 = 27.
  6. Final Answer: Substituting the cube root of 2727 into the derivative, we get g(27)=433g'(27) = \frac{4}{3}\cdot 3.
  7. Final Answer: Substituting the cube root of 2727 into the derivative, we get g(27)=(43)3g'(27) = (\frac{4}{3})\cdot 3. Multiplying (43)(\frac{4}{3}) by 33, we get g(27)=4g'(27) = 4. This is the final answer.
