The square root of a negative number is an imaginary number. Its possible to find but I don't think you would need to know it unless your in a high level math class. I would go with impossible if I were you.

To get square root of -5, you just have to place -5 inside the square root symbol. However, because it is prohibited to have negative integers inside square root symbols, you have to extract it using an imaginary number, symbolized by the letter i. Therefore, the answer to your problem is: i square root -5.
I hope you understand.

5 is not a perfect square & so its root is not a whole number, square root of 4 is 2 & 9 is 3 , hence square root of 5 will lie between 2 &3, nearer to 2 since 4 is more closer to 5 . now take the desimals like 2.1,2.2,..... & square them , we observe that 2.2 square is nearer to 5 & now try for 2nd decimals with 2.21,2.22,2.23.......... ans is 2.23 now the negative sign is left whose root is written as 'i' meaning imaginary. [ans=2.23i]

It is imposable because negitive five is a negitive number. a square root is finding what two of the same numbers multiply together to equal the product. As you know a negitive times a postive number equals a negitive number (ie:5 x -1) so it is imposable to multiply two negitive numbers(which would give one a positiave number) and give one a negitive number.
Sumorization= Imposable
