What about plain old
x = -10?-10 ^ 2 = 100
-10 ^ 3 = -1000
-10 ^ 5 = -100000Isn’t that the joke?
That’s what he wrote, I imagine.
It is, but with imaginary numbets

10 * i^2 is -10.
of course, but this problem is solvable without any understanding of complex numbers, and 10*i^2 is a really clunky, multi-operation expression whereas -10 is just an integer.
simplifying one’s answers is standard practice and any grader who received the answer in the OP would be obligated to point out that while technically correct, they’re missing the basic fact that the answer is -10.
The Rube Goldberg comment is apt as the solution is absurdly complicated and overengineered for the task it performs.
Yes that’s what the thing you are looking at is built upon.
Nothing gets past you eh?
people being pedantic showoffs doesn’t really register as humor for me, TBH
That’s true, the OOP is being quite snarky with their comment on a post where someone’s had a genuine basic doubt
Yeah exactly you’re right, why overcomplicate the problem like the Reddit comment did? I guess that’s just typical Reddit thinking that being pendantic and using lots of fancy words and long explanations makes you smart.
Nah just boiler plate autism.
no
That was my immediate thought too.
Boooooring
Wait, isn’t x just -10 if x^3 is not 1000?
yes, it is
that is a very long way to write -10
My brain
It hurts
That’s because the explanation was about 10 times as complicated as it needs to be
Math pun intended?
He is trolling with overcomplicating
What an extremely unnecessary explanation. As a math teacher I would have deducted points for this answer.
“show your work”
Malicious compliance intensifies
Unless I was in that clas where we had to write mathematical proofs. I HATED those. Sure, you solved the question but write out this complicated reason for why your answer is the correct answer.
No definition what values are suitable for x.
x has to be -10, right? Or am I missing something?
Yeah, I think the point is that the person answering was wrong/over complicating. If x=10i, then x^2 would be -100 (or potentially -10 depending on what you think the ^2 is applied to).
They said x=10i^2, not 10i. Difference is it equals -10, and they chose not to simplify.
They’re correct, it’s just overcomplicated as fuck in ways that are correct but completely irrelevant to the question.
The answer in the meme (10i^2) is -10
Depends on what are the allowed values for x are. Real numbers, complexe numbers, binary or I made up my own numbers ;)
Probably what they were going for, but there are literally an infinite number of exotic arithmetic spaces you could ask this question in. For example, x=10 works in any ring with a modulus greater than 100 and less than 1000.
fortunately math problems are administered in the context of the class, so it will be pretty obvious that it’s in the complex plane.
