Let's go through each part of this question step by step.
### Part (a)
We are asked to find the value of [tex]\(\sqrt{3} + \sqrt{5}\)[/tex].
So,
[tex]\[
\sqrt{3} + \sqrt{5} \approx 3.968118785068667
\][/tex]
This is the numerical result.
### Part (b)
We are asked to find the value of [tex]\(\sqrt{7} (\pi - \sqrt{5})\)[/tex].
So,
[tex]\[
\sqrt{7}(\pi - \sqrt{5}) \approx 2.395793098966465
\][/tex]
This is the numerical result.
### Part (c)
We are asked to find the value of [tex]\(\pi (2 - 3\pi - \sqrt{11})\)[/tex].
So,
[tex]\[
\pi (2 - 3\pi - \sqrt{11}) \approx -33.7451119721828
\][/tex]
This is the numerical result.
By following the steps and calculating the expressions accordingly, we get the required results for each part of the question.
