What is the unit digit of <math>1434^{1434}</math>?
+
Let <math>S</math> be a finite set endowed with an associative binary operation <math>*</math> such that <math>a*b*a=b</math> for all <math>a,b\in S</math>. Prove that <math>|S|</math> is a power of <math>2</math>.
 
 
==Solution
 
Since 1434 ends in a 4, all we need to know is the units digit of powers of 4
 
4^1 = 4
 
4^2 = 16
 
4^3 = 64
 
4^4 = 256
 
As you can see every ever power of 4 has a units digit of 6 and every odd power of 4 has a units digit of 4. As 1434 is even 1434^1434 has a units digit of 6
 
 
 
==Solution 2==
 
If you want to know where the king of ohio is you have to start mewing to skibidi and have a legendary mog battle with the all-knowing Ohio sigma known as master goonway who mews over the betas with l rizz and a level 0 on the rizz-o-meter. So stay skibidi and be the sigma over all betas so you can be the Ohio rizzler.
 
 
 
also listen to Eminem clean
 
 
 
oh and never gonna give you up
 
never gonna let you down
 
never gonna turn around and desert you
 
never gonna make you cry
 
never gonna say goodbye
 
never gonna tell a lie
 
and hurt you
 
 
 
==Solution 3==
 
By the Ohio theorem, the answer is clearly not 6969420, or 42069. We can apply the Skibidi Slicers theorem to then, get the answer of <math>\boxed{\text{Baby Gronk - Livvy Dunne}}</math>
 
 
 
==Solution 4==
 
Sigma ohio inequality states that <math>b\text{Sigma}^{a}\leq \sqrt{\text{Ohio}^{ab} \text{Mogging caseoh}} \leq +10000b \text{aura}</math>
 
<math>\forall a,b \in \mathbb{SIGMA}</math>
 
<math>\boxed{\textbf{(D)}+\infty \text{ aura}}</math>
 
 
 
==Solution 4==
 
Using the brainrot theorem, we can see that the spheres are forming an exponential function, so we divide by the rizzler, and then multiply it by ohio. So the answer is <math>\boxed{D, 1434}</math>
 
 
 
==Solution 5==
 
?????????? wtf bro <math>\textbf{(D)}</math>
 
 
 
==Solution 6==
 
we do the thing (compose the gyatt theorem into the rizzler function) and it works, then apply fanum tax and tensor product <math>\otimes</math> with the mythical Ohio Grassman to yield
 
<math>\boxed{\textbf{(D)}\frac{1}{0}}</math>
 
 
 
==Solution 73==
 
because skibidi toilet will be mine now, we use the Fanum Formula to find that the area of triangle OHI with O as its right angle has area 1434^2. From here, we plug it into the Rizzler Remainder Rule to find that the perimeter of pentagon SIGMA can equal none of the answer choices but <math>\boxed{{(Z)} Gyatt}</math>
 
 
 
==Solution 1434==
