I was scanning google images of math tee shirts when I found this one. 
And, including the photo, I have found three different answers. I should say just specifically regarding the derivative of $\pi^5$. Desmos app looks like it has it at $0$. And Wolfram mentions the transcendental aspect of the number. In this case I guess my question is in conceptualising that $\pi$ is a constant and therefore the derivative of a constant is $0$.

Of course the derivative of $\pi^5$ is zero – D_S Jun 07 '17 at 17:44

the derivative of $\pi^5$ is equal to Zero, since this is a constant – Dr. Sonnhard Graubner Jun 07 '17 at 17:45

1I'm voting to close this question as off-topic because it's really stupid question – D_S Jun 07 '17 at 17:45

1there is no stupid question. he simply didn't get the joke @D_S – Saketh Malyala Jun 07 '17 at 17:45

I don't get how it's a joke but okay – D_S Jun 07 '17 at 17:46

the shirt is a joke... @D_S – Saketh Malyala Jun 07 '17 at 17:46

3On an unrelated note, I really have no idea who would buy this. A TA who likes making fun of his students, maybe? Most people wouldn't even get the joke and of those of us who do, it seems (at least to me) quite insulting. For comparison, here is a much better physics joke shirt that I find hilarious. – Jun 07 '17 at 18:00

@Bye_World well i mean, its for people who have a certain sense of humor – Saketh Malyala Jun 07 '17 at 18:37

2@Bye_World While we're at it, this shirt and this shirt are quite awesome and much better than the one here – Simply Beautiful Art Jun 07 '17 at 22:53

It looks like a Reader's Digest joke. – Felix Marin Jun 09 '17 at 03:12

@SimplyBeautifulArt Theorem: "All odd numbers $> 1 $ are primes". Proof: $3$ is prime, $5$ is prime, $7$ is prime, $9\ \color{#f00}{\texttt{is not}}$ prime ( don't worry: it's an experimental error ),$11$ is prime$\ldots$ – Felix Marin Jun 09 '17 at 03:18

I'm pretty sure by the chain rule it should be
$$\frac d{dx}(\pi^5+x^4)=5\pi^4\frac{d\pi}{dx}+4x^3$$
From here its just a matter of deciding which $\pi$ function we are referring to!

Maybe, it' s something like $\left.{\mathrm{d}x^{5} \over \mathrm{d}x}\right\vert_{\ x\ =\ \pi} = 5\pi^{4}$. – Felix Marin Jun 09 '17 at 03:00

That's just a joke making fun at students who incorrectly use the power rule on powers of constants.
But the derivative of a constant is 0, because a constant does not change with respect to the variable, hence CONSTANT.

3It also pokes fun at the common student use of "derive" instead of "differentiate". – Erick Wong Jun 07 '17 at 17:47

2Eager to know, who was the downvoter. I have balanced it though :-) – Vidyanshu Mishra Jun 07 '17 at 18:11

@ErickWong, it's even worse: derivation is a special kind of function that satisfies the Leibniz product rule. – Santiago Jun 07 '17 at 18:36
