Well let's break it down:

  • πŸ” + πŸ” + πŸ” = 18
    • 3πŸ” = 18
    • πŸ” = 6
  • πŸ” + (🍟 β€’ 🍟) = 5
    • 6 + 🍟^2 = 5
    • 🍟^2 = -1
    • 🍟 = I
  • πŸ₯€^🍟 - πŸ₯€ = 3
    • πŸ₯€^i-1 = 3
    • πŸ₯€ = 3^1/(i-1)

Simple!

Wait, what happened in the second to last bullet point? You can't convert a power like that when subtracting (you can when dividing).

It's like you'd convert "2^4 - 2" into "2^(4-1)", which gives two different results (14 vs 8).

For those curious, I threw πŸ₯€^i - πŸ₯€ = 3 into wolfram.

πŸ₯€ β‰ˆ -2.97983 + 0.0388569 i... or πŸ₯€ β‰ˆ 0.27972 - 0.748461 i...

You're right, idk what I was thinking there πŸ˜•

I think they're saying no one can give the real answer to this... which is technically true because the answer is imaginary.

you forgot the Β± when square rooting:

🍟 = ±i

this is because i Γ— i = -1 and -i Γ— -i = -1

[–] anti_antidote@lemmy.zip 3 points 1 year ago

Bah, yes I forgot about that

[–] ichmagrum@feddit.de 10 points 1 year ago* (last edited 1 year ago)

🍟 = I

Don't you mean 🍟 = i?

And just like that, I'm back to junior high grumbling about the concept of imaginary numbers.

Fuck you, y'all made up! 🀣

[–] anti_antidote@lemmy.zip 1 points 1 year ago

Lol I didn't quite get my math right, but it still involves imaginary numbers. Fun fact! Any 3D game you've played in the past probably quarter century doesn't just use 1 dimension of imaginary numbers, but 3 to represent 3D rotation! Quaternions are difficult to visualize since it's a 4-dimensional quantity but they're perfect for representing rotation in 3D space without suffering from gimbal lock like rotation matrices.

I fucked around, and this is what i got:

πŸ” + πŸ” + πŸ” = 18

=> πŸ” = 6

πŸ” + ( 🍟 Γ— 🍟 ) = 5

🍟² = -1

=> 🍟 = ±i

(πŸ₯€^ 🍟) -πŸ₯€= 3

case 1: (πŸ₯€^ i) -πŸ₯€= 3

case 2: (πŸ₯€^ -i) -πŸ₯€= 3

at this point, i just used wolfram to get both:

=> {

πŸ₯€ β‰ˆ -2.97983 + 0.0388569 i,

πŸ₯€ β‰ˆ 0.27972 - 0.748461 i

}

Curiously, case 1 and case 2 return the same 2 values...

Correction, 99% of European people can’t solve this. For Americans this just a regular breakfast

Y'all bitch about math class but it you replace x, y & z withπŸ”πŸŸπŸ₯€ and suddenly you're all doing math for fun

A quarter pounder with cheese

[–] edinbruh@feddit.it 2 points 1 year ago

You mean a cheese royal?

Math now supports Unicode variables! The progress we all need.

Looks like you need a refill.
