Explain why it is not possible to take a square root of a negative number?

Actually, it is. It just depends within what set you are doing your calculation, that is, what do you consider an "acceptable solution".
The question of the square root means, which number, when squared, gives a specific number. Within the real numbers, the square of a positive number is positive, the square of a negative number is also positive. Therefore, there are no real numbers whose square is negative.
Within the complex numbers, the square root of -1, for example, is i (the "imaginary unit") - that is, i2 = -1. Similarly, the square root of -4 is 2i, the square root of -9 is 3i, the square root of -2 is (square root of 2 times i), etc.
In some areas, complex numbers are acceptable as solutions, in other areas, they are not. In the same vein, negative numbers are acceptable as solutions to certain problems, but not for certain other problems.

Is it possible to find the square root of a negative number explain why or why not?
This is not possible, because any number squared would be positive, not negative.
Is it possible for a to be a negative number in the equation a squared equal b explain why or why not?
Of course it is. 'a' can be any positive or negative number, and 'b' is its square.That's no problem.What is difficult is for 'b' to be a negative number in the same equation.No real number for 'a' can produce a negative 'b'.
Why is it impossible to square a negative number?
you can square a negative number but you can not square root a negative number
Is it possible to find the square root of a negative number in the real number system?
No. There is no real number which multiplied by itself forms a negative number.A negative times a negative is a positive, and only a positive times a negative is a negative.However, in calculus there is an "imaginary value" (called i ) which represents the square root of -1.Square roots of larger negative numbers are represented by the square of the absolute value times i .
Is it possible that square pyramid have all face of square explain?
no it is not possible

Can the square of an integer be a negative number explain?
No, any 2 negative numbers multiplied together equal a positive number
Why is it impossible to square a negative number?
you can square a negative number but you can not square root a negative number
Why is it there are 2 roots in a square root?
There are two possible answers because if you square a negative number, you will get a positive answer.

Why is it impossible to get a negative answer when you square any number?
V kno that- x- is +. Now when u sqare a negative no it means occouring 2 times and cancel out each other. For example- -2 x -2=4 ============================ (a second answer.) Every real number is either negative, positive or zero. When you square a number, you multiply it by itself, so if you square a negative number, you are multiplying a negative by a negative which gives a positive. If you square a positive, you multiply a positive by a positive and get a positive. If you square 0 , get 0. Therefore, in no case is the answer negative. ( It is harder to explain why a negative times a negative is positive.)
Explain why the square root of 64 has a positive and a negative value?
That simply means that there is both a positive and a negative number which, when squared, gives you 64.
Is the square root of -25 irrational or complex?
you cant get the square root of a negative number. nothing times itself would equal a negative number. if you have √-25 then its not possible. If you have -√25 then you take the square root of 25 and make it negative, so then it would be -5
Is it possible for a standard deviation to be negative?
no it is not possible because you have to take the square of error that is (x-X)2. the square of any number is always positive----------Improved answer:It is not possible to have a negative standard deviation because:SD (standard deviation) is equal to the square of V (variance).
Is it possible that square pyramid have all face of square explain?
no it is not possible
What is an example of an imaginary number?
An imaginary number is a number that cannot exist. An example of an imaginary number would be: the square root of negative nine, or any negative number. When I try to think of any two of the same numbers that would multiply together to be negative nine, all I can think of is 3 or -3. when I square both of those numbers, I get the number 9, not -9. When I multiply two negatives together, I get a positive number, therefore there is no possible way to get the square root of -9, or any negative number. They are used to explain extra-dimensional theories. (such as cheese, flippantly). 3i
