Square Matrix
A matrix in which the number of rows is equal to the number of columns, say n, is called a square matrix of order n. In this square matrix of order n the elements a 1 1 , a 2 2 .......a n n is called the principal diagonal or the leading diagonal. The elements a 1 1 , a 2 2 ,.....

Question : what is the square root of '-x' (minus X)
Answer : what you define as 'easy' is not easy at all. In fact, it is not possible at all! What you are dealing with is a special branch of mathematics known as 'complex numbers', which is a factor of Specialist Mathematics. The answer is 'i' , which stands for imaginary (since square roots of negatives do not exist). But this is the correct answer- just check any Specialist Mathematics textbook. Hope this helps yo...
