please explain with Differentiation rule

Solution

The given function is n(t)=3t25t3/2n(t) = 3 \sqrt{t^2} - \frac{5}{t^{3/2}}.

To differentiate this function, we will follow these steps:

  1. Simplify the function (if possible):
    • t2=t\sqrt{t^2} = t, since tt is typically taken to be non-negative in this context.
    • Rewrite the second term 5t3/2\frac{5}{t^{3/2}} using negative exponents: 5t3/2=5t3/2\frac{5}{t^{3/2}} = 5t^{-3/2}.

Thus, the function becomes: n(t)=3t5t3/2n(t) = 3t - 5t^{-3/2}

  1. Differentiate each term separately:

    • For the term 3t3t: Use the power rule, ddt(tn)=ntn1\frac{d}{dt}(t^n) = nt^{n-1}. ddt(3t)=31t11=3\frac{d}{dt}(3t) = 3 \cdot 1 t^{1-1} = 3
    • For the term 5t3/2-5t^{-3/2}: Use the power rule. ddt(5t3/2)=5(32)t3/21=152t5/2\frac{d}{dt}(-5t^{-3/2}) = -5 \cdot \left( -\frac{3}{2} \right) t^{-3/2 - 1} = \frac{15}{2} t^{-5/2}
  2. Combine the differentiated terms: Add the derivatives of each term to get the derivative of the entire function. n(t)=3+152t5/2n'(t) = 3 + \frac{15}{2} t^{-5/2}

So, the derivative of n(t)=3t5t3/2n(t) = 3t - 5t^{-3/2} is n(t)=3+152t5/2n'(t) = 3 + \frac{15}{2} t^{-5/2}.
