Problem

\( f^{\prime}(2), f^{\prime}(x) \) ج \( f(x)=\left(x^{3}+3 x^{2}-3\right)^{\frac{3}{2}} \)

Solution

Step 1 :\(f'(x) = \frac{3}{2}(x^3 + 3x^2 - 3)^{\frac{1}{2}} \times (3x^2 + 6x)\)

Step 2 :\(f'(2) = \frac{3}{2}(2^3 + 3(2)^2 - 3)^{\frac{1}{2}} \times (3(2)^2 + 6(2))\)

Step 3 :\(f'(2) = \frac{3}{2}(8 + 12 - 3)^{\frac{1}{2}} \times (12 + 12)\)

Step 4 :\(f'(2) = \frac{3}{2}(17)^{\frac{1}{2}} \times 24\)

Step 5 :\(f'(2) = 36\sqrt{17}\)
