There is a little Magpie-lark that keeps tormenting the little dog next door. It sure looks like it's the bird teasing the dog. But are they that smart?

Evaluate the limit


4) lim square root of x-2 over square root of x^2 - 4x -4
X-->2
5) lim sq root of 1- 8x^3 over sq rt 1-4x^2
X--->1/2
6) lim sq rt of x -sq rt of 2 over x^2 - 2x
x--->2
7) lim 2 - cube root of x over (sq rt of x - 4) - 2
x---->8
8) lim x^2/3 -(2sq rt of x) over 4 - (16/x)
x--->8

In the 1930 in Khujut Rabula on the outskirts of Bagdad, some people was digging in a little hill. They found remains of a tower from the time of Partert.
The museum of Irak then began to do archaeological excavations in the area. A German archaeologist, named W. Kö***, then discover curious things who seems to be like a cell in a modern pocket torch!
He found out that they had found remains of four similar ”batteries” near the old city Seleuca, an area down the river. At a visit in The Berlin museum he discovered several not assembled parts, like a cylinder of copper, sticks of iron and asphalt to feed ten likely ”batteries”, probable used in a series connection

I had an interesting dream. I am not an expert in math and barely passed calculus. I want to find out the reasoning of why this is always true. So please Math wizards or experts help me solve this logic.

My dream was revolved around the number 6 and # 9. For some reason I could figure out that any number in any sequences (except starting with 0) would always come up with a whole number. Example: Divide this number by 9 in any sequence you like and you will always get a whole number, but you have to use all of these numbers.

I would like to know who can solve the answer to this and the reasoning why this is always true. My dream told me the answer to this and thought it was amazing but its so simple and not even complex. Do people have crazy dreams like this?
