un joyero vende 13 anillos de oro y 18 de plata por 9405 euros. sabiendo que el anillo de oro cuesta el triple que el de plata ¿
SpyIntel [72]
To solve this problem you must apply the proccedure shown below:

 1. You have that:

 - He sales 13 gold rings and 18 silver rings in 9405 euros.
<span> - The cost of the silver ring is three times the cost of the gold ring.

 2. Keeping the information above on mind, you have the following system of equations:

 x: the gold ring.
 y: the silver ring.

 x+y=</span>9405
<span> x=3y

 3. Then, you have:

 (3y)+y=9405
 y=9405/4
 y=2351.23 euros

 x=3y
 x=3(</span>2351.23)
<span> x=7053.75 euros

 The answer is: 
 - Gold ring=</span>7053.75 euros
 - Silver ring=2351.23 euros<span>

Find an integer x such that 0&lt;=x&lt;527 and x^37===3 mod 527
Greeley [361]
Since 527=17\times31, we have that

x^{37}\equiv3\mod{527}\implies\begin{cases}x^{37}\equiv3\mod{17}\\x^{37}\equiv3\mod{31}\end{cases}

By Fermat's little theorem, and the fact that 37=2(17)+3=1(31)+6, we know that

x^{37}\equiv(x^2)^{17}x^3\equiv x^5\mod{17}
x^{37}\equiv(x^1)^{31}x^6\equiv x^7\mod{31}

so we have

\begin{cases}x^5\equiv3\mod{17}\\x^7\equiv3\mod{31}\end{cases}

Consider the first case. By Fermat's little theorem, we know that

x^{17}\equiv x^{16}x\equiv x\mod{17}

so if we were to raise x^5 to the nth power such that

(x^5)^n\equiv x^{5n}\equiv x\mod{17}

we would need to choose n such that 5n\equiv1\mod{16} (because 16+1\equiv1\mod{16}). We can find such an n by applying the Euclidean algorithm:

16=3(5)+1
\implies1=16-3(5)
\implies16-3(5)\equiv-3(5)\equiv1\mod{16}

which makes -3\equiv13\mod{16} the inverse of 5 modulo 16, and so n=13.

Now,

x^5\equiv3\mod{17}
\implies (x^5)^{13}\equiv x^{65}\equiv x\equiv3^{13}\equiv(3^4)^2\times3^4\times3^1\mod{17}

3^1\equiv3\mod{17}
3^4\equiv81\equiv4(17)+13\equiv13\equiv-4\mod{17}
3^8\equiv(3^4)^2\equiv(-4)^2\mod{17}
\implies3^{13}\equiv(-4)^2\times(-4)\times3\equiv(-1)\times(-4)\times3\equiv12\mod{17}

Similarly, we can look for m such that 7m\equiv1\mod{30}. Apply the Euclidean algorithm:

30=4(7)+2
7=3(2)+1
\implies1=7-3(2)=7-3(30-4(7))=13(7)-3(30)
\implies13(7)-3(30)\equiv13(7)equiv1\mod{30}

so that m=13 is also the inverse of 7 modulo 30.

And similarly,

x^7\equiv3\mod{31}[/ex] [tex]\implies (x^7)^{13}\equiv3^{13}\mod{31}

Decomposing the power of 3 in a similar fashion, we have

3^{13}\equiv(3^3)^4\times3\mod{31}

3\equiv3\mod{31}
3^3\equiv27\equiv-4\mod{31}
\implies3^{13}\equiv(-4)^4\times3\equiv256\times3\equiv(8(31)+8)\times3\equiv24\mod{31}

So we have two linear congruences,

\begin{cases}x\equiv12\mod{17}\\x\equiv24\mod{31}\end{cases}

and because \mathrm{gcd}\,(17,31)=1, we can use the Chinese remainder theorem to solve for x.

Suppose x=31+17. Then modulo 17, we have

x\equiv31\equiv14\mod{17}

but we want to obtain x\equiv12\mod{17}. So let's assume x=31y+17, so that modulo 17 this reduces to

x\equiv31y+17\equiv14y\equiv1\mod{17}

Using the Euclidean algorithm:

17=1(14)+3
14=4(3)+2
3=1(2)+1
\implies1=3-2=5(3)-14=5(17)-6(14)
\implies-6(14)\equiv11(14)\equiv1\mod{17}

we find that y=11 is the inverse of 14 modulo 17, and so multiplying by 12, we guarantee that we are left with 12 modulo 17:

x\equiv31(11)(12)+17\equiv12\mod{17}

To satisfy the second condition that x\equiv24\mod{31}, taking x modulo 31 gives

x\equiv31(11)(12)+17\equiv17\mod{31}

To get this remainder to be 24, we first multiply by the inverse of 17 modulo 31, then multiply by 24. So let's find z such that 17z\equiv1\mod{31}. Euclidean algorithm:

31=1(17)+14
17=1(14)+3

and so on - we've already done this. So z=11 is the inverse of 17 modulo 31. Now, we take

x\equiv31(11)(12)+17(11)(24)\equiv24\mod{31}

as required. This means the congruence x^{37}\equiv3\mod{527} is satisfied by

x=31(11)(12)+17(11)(24)=8580

We want 0\le x, so just subtract as many multples of 527 from 8580 until this occurs.

8580=16(527)+148\implies x=148
