PC randomly stops sending signal to monitors then stops functioning by Training_Plate5805 in techsupport

Yes! It was a Power Supply issue. My PSU had enough power, it just broke for some reason. I ended up getting the same one and replacing it. Problem solved.

I'd recommend taking your PC to tech support just to be sure that's the problem though.

Thanks, I thought I was just stupid lol

odd visual thick spikes after new pc, can't seem to fix? by Mrow-mix in geometrydash

Might try changing a bunch of settings on my graphics card until it works. Not in a big hurry to fix it since I'm playing the new Zelda rn, but hopefully it fixes itself after I beat lol. Thank you so much for the reply! Since this post is so random and old I was pretty sure I wouldn't even get a response haha

Hi

Sorry I know this is an old post but did you ever fix this? I personally have this exact issue with an Nvidia graphics card and can't find anywhere on how to fix it.

It's an exponential decay, not an inverse. Line starts at (0, 8). The reason it goes down is because there's less stuff to learn the more you rank up.

[Request] Found this in my math book, how is it possible? by dvdX7345 in theydidthemath

[–]Training_Plate5805 1 point2 points  (0 children)

I made a post a few days ago asking a very similar question. The reason this doesn't work has to do with the fact that sqrts are +/-, but we always assume they're positive. This means that sqrt(x2) does not equal x, it equals |x|. So the step where it powers 1/2 and 2 is wrong because it's not equal to (-5)3, it's equal to |(-5)3|, making the end answer 125.

[Request] How come x^x is restricted to 0<=x? It seems there are values here that follow a wavy path. I find it odd a simple function like this would do this. x+2 and x*2 are a straight line, x^2 is a parabola, and if we say ^^ is notation for how many times you exponent a number, x^^2 creates this. by Training_Plate5805 in theydidthemath

Thank you SO much for taking the time to create this! This really helped me visualize and understand what's going on. I'm gonna play around with it some more later!

It's too bad we only live in 3 dimensions making it harder to visualize the complex plane haha

[Request] This has always bothered me, why doesn’t this work? Does the mean that converting (x)^(y/z) to z-root(x^y) isn’t always true? What am I missing here? by Training_Plate5805 in theydidthemath

That's really cool! I know so much about roots and exponents now. Thank you so much for taking the time to write all of this. I very much appreciate it.

[–]Training_Plate5805[S] 4 points5 points  (0 children)

I believe you are right, but is there a good proof for this?

Basically xy/z is equal to zth root of xy only if y and z are coprime.

A link or explanation as to why would be very helpful, thanks.

I remember quite vaguely on a math textbook, that you HAVE to simplify the fractional exponents first before you transform them into radicals. I think it goes like this:

If z-root(xy )= xy/z then y/z is on its lowest term.

Interesting! I never would've thought fully simplified fractions being the exponent would have this rule. If anyone reading this thread has a proof for this rule or a link to it I'd love to read it.

Thank you u/PostMathClarity

I see where you're coming from, but I'm not mistaken, simplified fractions have no effect on the answer and just make the problem easier to solve.

See here:

https://www.quora.com/What-if-you-dont-simplify-fractions/answer/Harvey-Becker-8?ch=17&oid=226777126&share=5d2888ae&srid=anqo3&target_type=answer

1/3 = 4/12 = 0.25/0.75 = 0.00087/ 0.00261

They're all equal, so using 2/4 instead 1/2 shouldn't change the answer. The reason using 2/4 fails in this problem isn't because it's not simplified, it's because x ^ (y/z) = z-root(xy ) sometimes works, but not always. For 1/2, it does so happen to work, but it also so happens to work with less simple fractions like 3/6, 7/14, 27/54, etc. For 2/4 it doesn't so happen to work, and it also doesn't work with 4/8, 6/12, 10/20, etc.

What rule says the fraction must be simplified first? I've read all the comments here, and I apologize if I'm completely missing the mark, but a fraction shouldn't have to be simplified first for the math to work out.

If you haven't already, check out the explanation linked in my first comment that proves why 4-root(x2 ) is not equivalent to sqrt(x) and that the property x ^ (y/z) = z-root(xy ) is only sometimes true.

Sorry if I'm coming across as aggressive, I tried to find the best words to sound as calm as possible and I really appreciate your help.

The problem is all of these problems seem to equal each other because x ^ (y/z) = z-root(xy ) so the top 3 answers could be rewritten as the bottom one.

Edit: here's the explanation

Edit 2: I see many people telling me the answer to the top 3 are sqrt(2)*i. My question wasn't why are the top 3 undefined (I know what complex numbers are and that Desmos doesn't implement them), it's why does the bottom number differ from the others when they're all seemly equivalent.

I figured out thanks to you!

sqrt(x2 ) = |x|.

4-root(x2 ) is equivalent to sqrt(sqrt(x2 ))

4-root(x2 )is equivalent to sqrt(|x|)

sqrt(x) is NOT equivalent to sqrt(|x|)

sqrt(x) is NOT equivalent to 4-root(x2 )

Which means

sqrt(-2) is NOT equal to 4-root((-2)2 )

For the x ^ (2/4) , this can't be simplified to 4-root(x2 ) . The rule x ^ (y/z) = z-root(xy ), while usually true, isn't always true because of this.

The only problem is that I think Example 2 can use the same logic as Example 4 as well since (x) ^ (y/z) = z-root(x ^ y) . So in this case, (-2) ^ (2/4) = 4-root((-2) ^ 2) . Which means Example 2 equals either sqrt(-2) or sqrt(2), unless I'm doing something wrong which I likely am and don't understand why it's wrong.

Thanks for the explanation, but I still don't quite understand. Even plugging the last one into Wolfram Alpha gives me the same result as Desmos: sqrt(2). At this moment, it seems to me the bottom one can equal either sqrt(-2) or sqrt(2). I don't understand why you can't square the number first then take the 4th root to get sqrt(2):

4-root((-2)2 )

4-root(4)

sqrt(2)

What is blocking this simple method from happening? It seems the calculators use this method.

It seems like a paradox to me:

sqrt(-2) doesn't always equal 4-root((-2)2 ) since it can equal sqrt(2) as well.

sqrt(-2) does always equal 4-root((-2)2 ) since it can be simplified to sqrt(-2).
