April 10th: The bill has been vetoed!
April 2nd: The politicians in Arizona are about to sign into law a bill that would mandate sites like e621 to either impose age verification on all users or be at a risk of lawsuits. Such system would be required to go through third party vendors, who in turn must go through a government database to verify every user's age. This is not only a major violation of privacy, but it also opens up a very real danger of identity theft through phishing schemes and other methods, not to mention that we would not be able to control any of that information to make sure it is permanently deleted after age verification is complete.
Unfortunately, Arizona is the state out of which e621 operates, which means that this law will almost certainly affect us if it is to pass. If want to help us ensure that this site can continue to serve you without being required to know who you are, please ask the Arizona governor to veto this bill.
Please, help us get the word out by letting others know about this issue.

We still have a Discord server, come talk to us!

A.√(√(224+96√5))を簡素化した
√x+√y になる。
xーyの値は__。
A.√(√(224+96√5)) is simplified into √x+√y
The value of x-y is ___.
まず96√5を2√11520と認めて、
a+b=224、ab=11520とおしたら
|aーb|=64を求めてa、bは144と80で
√(√(224+96√5))=√(√(√144+√80)^2)=√(12+4√5)
4√5を2√20と認めて、 x+y=12、xy=20とおしたら、
勘によってx、yりは2と10でしょう?
だから√(12+4√5)=√((√2+√10)^2)=√2+√10
First, let's accept 96√5 as 2√11520,
and let a + b = 224 and ab = 11520,
and find |a-b| = 64, so a and b are 144 and 80,
√(√(224+96√5)) = √(√(√144+√80)^2) = √(12+4√5)
Let's accept 4√5 as 2√20, and let x + y = 12 and xy = 20,
and by intuition x and y are 2 and 10, right?
So √(12+4√5) = √((√2+√10)^2) = √2+√10
最後に、
x=2 y=10
とx=10 y=2
2つ結果があって、xーy=8または−8で、つまり±8です。
In the end, with x=2 y=10 and x=10 y=2, there are the 2 results, x-y=8 or -8, which means ±8.
