The answer can be found at the link.

The solution to the root number actually asks which number is squared equal to the number in the root number.

For example 4, the answer is +2 and -2. 36, the answer is +6 and -6

The answer is that there are two numbers, but in general practical problems, positive numbers are used, but it also depends on the situation.

Not all numbers are squared out of the result of an integer, for example, 8, when you can't find the answer to an integer, you can try to split this number, that is, 8 = 4 * 2 = 4 * 2, and 4 can be squared ( 4 = 2), so it becomes 2 * 2, that is, 2 2.

This should be understood as simplification, a bit like the reduction of fractions. (This is my personal way of understanding, and it's okay if you don't understand it that way).

There are many more like this, e.g. 20= 4*5= 4* 5=2* 5=2 5

If it is like 72, we should give priority to a relatively large number like 36, that is, 72 = 36 * 2 = 36 * 2 = 6 * 2 = 6 2, so that it can be done in one step. Don't think about the decimal of 4 first, it will get a bit more troublesome.

Root number 27 = root number 9 * root number 3

Root number 9 = root number 3 * root number 3 = 3

So the root number 27 = 3 * the root number 3

Root number 8 = root number 4 * root number 2

Root number 4 = root number 2 * root number 2 = 2

So root number 8 = 2 * root number 2

So, root number 27 = root number [(3 2)*3] = 3 root number 3

In the same way, 8 = 2 3

(5 root number 2-8 root number 2) * root number 3-3 2 root number 6 (-3 root number 2) * root number 3-3 2 root number 6

3 root No. 6-3 2 root No. 6

9 2 root number 6

150- (4x32x3)- 27/2 = 5 6-8 6-3/2 6 I wrote it hard, and I did it myself. Wish. Or "like" it.

The root number is constant and non-negative, so both root numbers are 0

a=1/3 b=27

The arithmetic square root of ab=9ab=3 or -3

Well, because a=2006, 2005=a-1, 2007=a+1, 2008=a+2

So 2005 2006x2007x2008+1=(a-1)a(a+1)(a+2)+1

So 2005 2006x2007x2008+1=(a-1)a(a+1)(a+2)+1=[(a-1)(a+2)][a(a+1)]+1=[(a +a)-2](a +a)+1=(a +a) -2(a +a)+1=(a +a-1).

So the original formula = (a + a-1) - a = a-1 = 2005

The key is to convert the number in the original formula into a formula instead of a, and then simplify it to make the original formula simple.

Don't ignore "a=2006"

Do I understand how to write this? If you don't understand, let me know.

Ling a = 2006

2005×2006×2007×2008+1=[(2006-1)(2006+2)][2006(2006+1)]+1==[a-1)(a+2)][a(a+1)]+1

The rest of the story knows.

1.If the decimal part of 5 + root number 11 is a, and the decimal part of 5 - root number 11 is b, find the value of a+b.

2.It is known that the real number a satisfies |2006-a|+ root number a-2007=a, find the value of a-2006 squared.

3.If the cube root of 200a is an integer, then what is the largest negative integer a?

4.Knowing that the root number x square of the equation -5 times = ax-1 has a negative root and a is greater than 0, find the range of values of a.
