Who can solve the super puzzle Difficult to solve the puzzle

If you divide it from the level of hidden users, it can be divided into three types, namely high anonymity, normal anonymity, and transparency.

1) Highly anonymous** does not change the client's request, so that the server looks like a real client browser is accessing it, then the client's real IP is hidden, and the server will not think that we are using**.

2) Ordinary anonymity** can hide the real IP of the client, but it will change our request information, and the server may think that we are using**. However, when using this kind of **, although the visited ** cannot know your IP address, it can still know that you are using**, of course, some web pages that can detect IP can still find your IP.

3) Transparency**, which not only changes our request information, but also transmits the real IP address.

The level of concealment of the identity of the user is highly anonymous and hidden, followed by ordinary anonymity, and transparency at worst.

So you have to see which one you use. If you don't know which one you are. Actually, don't worry.

ADSL Internet access is assigned dynamic IPs. You don't have to use ** at all. Even if your IP is blocked.

Disconnect and reconnect again. Due to IP dynamics. No one can find your address.

PS: It's not a problem, and it's not a super problem.

Can't find you because you are a dynamic IP Every time you go online, you will be assigned a different IP, so you can only find out which region your IP is from, and you can't find out who it is, and the IP address you use every time you connect to the Internet is different.

Even if you find the address of **, you won't find the user's address.

1+3+5+7+。。= how many n numbers are squared, and the number added is 2n-1, added to 13, n = 7, and = 7

Add to 31, n=16, and number = 16

Subtract 15+17+. 29+31=16²-7²

The algorithm is f(xy)=xy 0=1, and xy takes the adjacent prime number (also called prime number).

The total weight left after eating 40g per pack is the total weight of the previous 3 packs, so the weight eaten is the total weight of the original two packs.

So it turns out that each pack weighs 40 5 2 = 100g

It is also possible to set the original weight of each pack x

5×(x-40)=3x

Solution x=100

Let the common edge ab be x, bring in the other edges with tan, cos, and sin, and then bring them into the Pythagorean theorem.

bc is 4x and db is x, available.

bc+20=db, that is, 4x+20=x

Solving this equation gives ab i.e. x

You can set ab=x

With tan = 3 4, we can calculate the length of BC (including x) and then the length of DB (also containing x).

Give you the value of the degree, and you can list the equation.

If the number of tens is x, then the single digit is x+2, then the two-digit number is 10x+x+2 and less than forty.

So: the answer is 2n, n can be a positive infinity, but n is a positive integer.

Because 2 = 1 + 1

So there are many, many stars in the sky.
