Ans: The exact value of, ${鈭�}_{鈭� 3}^{2} 鈥� \frac{x^{2} + 5}{2 x} d x = \frac{5 (2 (\ln 鈦� (2) + \ln 鈦� (鈭� 1)) 鈭� 2 \ln 鈦� (鈭� 3) 鈭� 1)}{4}$

Step by step solution

Step 1. Given information.

given expression,

${鈭�}_{鈭� 3}^{2} 鈥� \frac{x^{2} + 5}{2 x} d x$

Step 2. The objective is to determine the exact value of the definite integral.

The exact value is calculated as shown below,

${鈭�}_{鈭� 3}^{2} 鈥� \frac{x^{2} + 5}{2 x} d x = \frac{1}{2} {鈭�}_{鈭� 3}^{2} 鈥� x d x + \frac{5}{2} {鈭�}_{鈭� 3}^{2} 鈥� \frac{1}{x} d x = [\frac{x^{2}}{4} + \frac{5 \ln (x)}{2}]_{鈭� 3}^{2} = [\frac{5 \ln 鈦� (| x |) + \frac{x^{2}}{2}}{2}]_{鈭� 3}^{2} = \frac{5 \ln 鈦� (2) + 5 \ln 鈦� (鈭� 1) 鈭� 5 \ln 鈦� (鈭� 3) 鈭� \frac{5}{2}}{2} = \frac{5 (2 (\ln 鈦� (2) + \ln 鈦� (鈭� 1)) 鈭� 2 \ln 鈦� (鈭� 3) 鈭� 1)}{4}$

Therefore, the exact value is $\frac{5 (2 (\ln 鈦� (2) + \ln 鈦� (鈭� 1)) 鈭� 2 \ln 鈦� (鈭� 3) 鈭� 1)}{4}$

Step 3. Check:

The required graph is,
