Full solution

Q. Let h(x)=x5 h(x)=\sqrt{x^{5}} .\newlineh(4)= h^{\prime}(4)=
  1. Rewrite function: To find the derivative of the function h(x)=x5h(x) = \sqrt{x^5}, we first need to rewrite the function in a form that makes it easier to differentiate. The square root of x5x^5 can be written as (x5)12(x^5)^{\frac{1}{2}}.
  2. Apply chain rule: Now we apply the chain rule to differentiate the function. The chain rule states that the derivative of a composite function is the derivative of the outer function evaluated at the inner function times the derivative of the inner function. In this case, the outer function is u(1/2)u^{(1/2)} and the inner function is x5x^5.
  3. Differentiate outer function: Differentiating the outer function u(1/2)u^{(1/2)} with respect to uu gives (1/2)u(1/2)(1/2)u^{(-1/2)}. Then we differentiate the inner function x5x^5 with respect to xx, which gives us 5x45x^4.
  4. Combine derivatives: Now we combine the derivatives of the outer and inner functions. The derivative of h(x)h(x) is (12)(x5)12×5x4(\frac{1}{2})(x^5)^{-\frac{1}{2}} \times 5x^4.
  5. Simplify expression: Simplify the expression by combining like terms. This gives us (52)x(412)(\frac{5}{2})x^{(4 - \frac{1}{2})}, which simplifies to (52)x(72)(\frac{5}{2})x^{(\frac{7}{2})}.
  6. Evaluate at x=4x=4: Now we evaluate the derivative at x=4x = 4. We substitute xx with 44 in the expression 52x72\frac{5}{2}x^{\frac{7}{2}} to get 52(4)72\frac{5}{2}(4)^{\frac{7}{2}}.
  7. Calculate value: Calculate the value of (4)72(4)^{\frac{7}{2}}. Since (4)72(4)^{\frac{7}{2}} is the same as 47\sqrt{4^7}, and 474^7 is 1638416384, we take the square root of 1638416384, which is 128128.
  8. Multiply to get final answer: Now multiply (52)(\frac{5}{2}) by 128128 to get the final answer. (52)×128=5×64=320(\frac{5}{2}) \times 128 = 5 \times 64 = 320.
