That did not make sense.

It does not seem like a proper sentence.

Amyway, the five thread conversation is really making me sweat. I am out of practice.

I guess I am having problem with precision.

Hold on, I am eating. I will be checking up on this every few minutes.

What are you getting for

When you substitute a0 with 1 to 9?

If that is where you are having problems then do you want me to do one so you can see how to do it?

Actually I am trying to solve this equation:

(10^57-6)*a0 congruent to 0 (mod 59))

And to me it seems that every value of a0 is satisfying the equation

That is true 1 to 9 will all work but they will not all solve the problem.

Why should they all work? But not satisfy the problem????????????????????????

There are extra conditions on the problem that just multiplying by a0 does not handle.

Think of it like an extraneous root. Just because algebra gets an answer that does not mean it is a solution. Sometimes extraneous answers are produced. Checking by plugging in is always necessary.

Are the two answers as stefy said to plug a0 as 6 and 9

Is there a 116 digit solution too?

Hi;

Before we try to answer that, there are two more solutions. Can you find them?

Any hint?

I will show you how to check them, you will not need a hint. Have a good day at school and study hard.

Here is the number we find for a0 = 6:

Take the a0 and put it on the back of the answer. You get,

Now does 6 times that equal the original original number with the unit digit moved to the front?

That does equal the first number we found with the unit digit moved to the front. We have a solution! Check all the other possibles in the same way. You will find 4 solutions.
